Let's analyze the given question which asks us to find the word opposite in meaning, the antonym, of the word "Cynical". Understanding the meaning of the word "Cynical" and each option is key to finding the correct antonym.

Understanding the Word Cynical

The word Cynical describes someone who believes that people are motivated purely by self-interest; they are distrustful of human sincerity or integrity. A cynical person often questions the motives behind seemingly good actions, assuming there's an underlying selfish reason.

• Someone who is cynical tends to be pessimistic about human nature.
• They often express doubt or suspicion.
• Synonyms for cynical include sceptical, distrustful, pessimistic, and jaded.

Analyzing the Options for Antonym of Cynical

We need to find the word that represents the opposite trait of being cynical, which is being distrustful or doubtful of others' motives.

1. Scoffing: To scoff means to speak about something or someone in a scornfully derisive or mocking way. This is often an action associated with a cynical attitude, but it describes a behavior, not necessarily the core belief opposite to cynicism. It is not an antonym.

2. Incredulous: This means unwilling or unable to believe something. While related to disbelief, it often refers to a specific statement or situation, not necessarily a general distrust of human nature like cynicism. It is similar to sceptical, which is a synonym of cynical.

3. Credulous: This word describes someone who has or shows too great a readiness to believe things. A credulous person is easily convinced and tends to trust others readily. This is the direct opposite of being distrustful and sceptical of human sincerity, which defines a cynical person.

4. Sceptical: This means not easily convinced; having doubts or reservations. Sceptical is a synonym of cynical, meaning it has a similar meaning, not the opposite.

Finding the Opposite of Cynical

Based on the analysis, the word that is opposite in meaning to Cynical (distrustful, doubting sincerity) is Credulous (easily believing, trusting readily).

Therefore, the antonym of Cynical is Credulous.
