The given question involves analyzing two statements: an Assertion (A) and a Reason (R). Let's break down each component and determine the correct answer.

Assertion (A): The production of an organisation can be shown using a bar chart.

Reason (R): A bar graph can be converted into a pie chart.

Analysis:

Assertion (A): The bar chart provided shows the production data of an organisation across different years. A bar chart is a graphical representation used to show categorical data with rectangular bars. It is indeed a valid way to represent organisational production data over time.

Reason (R): A pie chart is another form of graphical representation that displays data in a circular graph. Each slice of the pie represents a proportion of the whole. Bar charts and pie charts are interchangeable if the data represents parts of a whole or categorical data distribution. Therefore, it is correct to say that a bar graph can be converted into a pie chart.

Conclusion:

Both the Assertion (A) and the Reason (R) are correct. Furthermore, the Reason (R) provides a correct explanation for why a bar chart can be represented as a pie chart. Hence, the most appropriate answer is:

Correct Option: Both (A) and (R) are correct and (R) is the correct explanation of (A).
