Two statements are given below and these are labelled as Assertion (A) and Reason (R).
Assertion (A): Vitamin C is destroyed by heating.
Reason (R): Vitamin C is water-soluble and heat-sensitive.
Select the correct answer from the following options:
Analyzing Vitamin C Stability When Heated
This question asks us to evaluate two statements, an Assertion (A) and a Reason (R), concerning Vitamin C and the effect of heating.
Evaluating Assertion (A): Vitamin C is Destroyed by Heating
Assertion (A) states that Vitamin C is destroyed by heating. This statement is scientifically accurate. Vitamin C, also known as ascorbic acid, is sensitive to heat and prolonged exposure can lead to its degradation. This is a crucial point when considering cooking methods, especially boiling, as much of the Vitamin C can be lost into the cooking water or broken down by the heat itself.
Evaluating Reason (R): Vitamin C is Water-Soluble and Heat-Sensitive
Reason (R) states that Vitamin C is water-soluble and heat-sensitive. This statement is also true.
- Water-Solubility: Vitamin C dissolves easily in water. This property contributes to its loss during cooking processes where food is boiled or steamed in large amounts of water.
- Heat-Sensitivity: As mentioned earlier, Vitamin C breaks down when exposed to heat. This sensitivity means that high temperatures, especially over extended periods, significantly reduce the vitamin's content in food.
Connecting Reason (R) to Assertion (A)
The question requires us to determine if Reason (R) correctly explains Assertion (A). Let's see how the properties mentioned in (R) cause the effect described in (A):
- Assertion (A) says Vitamin C is destroyed by heating.
- Reason (R) explains *why*: because Vitamin C is heat-sensitive.
The fact that Vitamin C is heat-sensitive directly explains why heating destroys it. The water-soluble nature also contributes to its loss during certain cooking methods, but the primary reason for its destruction *by heat* is its sensitivity to temperature.
Analyzing the Options
Based on our analysis:
- Both Assertion (A) and Reason (R) are true statements.
- Reason (R) provides the correct scientific basis (heat-sensitivity) for why Assertion (A) is true (destruction by heating).
Therefore, the option that states both are true and (R) is the correct explanation of (A) is the accurate choice.
Important Questions from Assertion and Reasons (Notes)
- Given below are two arguments.
(I): A valid deductive argument that also has all true premises is called a sound argument
(II): A strong inductive argument that has all true premises is called a cogent argument
In the light of the above statements, choose the most appropriate answer from the options given below - Assertion(a): Rift valley represents a trough, depression or basin between two crustal parts.
Reason(r):Rift valley is a major relief feature resulting from faulting activities. - Assertion(A): The term suburban is used on a large scale and the residential areas lying within the rural-urban fringe are recognised as suburbans.
Reason(R): The people living in the urban clusters call themselves suburban dwellers. - Assertion and Reasoning Type
Assertion(A): After the II world war, lot of industries in Japan were developed in the coastal region.
Reasoning(R): The recovery of the industrialization after world war II in Japan was without a domestic raw material and export market in mind. - Assertion (A): Connectivity index expresses the number of links in a network as a ratio of the maximum number of links possible.
Reason (R): Higher values of the index indicate low level of connectivity and vice versa.
