Evasive is a word used to describe someone who avoids giving a direct answer or response to a question or situation. This behavior can often be seen as dishonest or suspicious. Let's take a look at why "honest" is the correct answer.

Honesty and Evasiveness are Opposites
The two words are antonyms, which means they are opposite in meaning. If someone is being honest, they are being truthful and forthcoming with information. In contrast, if someone is being evasive, they are avoiding the truth and being vague. Therefore, option B is the correct answer.

Examples of Evasiveness
When someone is evasive, they may use tactics such as changing the subject, giving non-committal answers, or avoiding the question altogether. For example, if someone asked a politician if they support a particular policy, and the politician responds with a vague statement that doesn't answer the question, they are being evasive.

Honesty is Valued in Society
Being honest is an important value in most societies. It is seen as a positive trait because it promotes trust and transparency. Evasiveness, on the other hand, can be seen as suspicious and untrustworthy.

Conclusion
In conclusion, being evasive means avoiding a direct answer or response, while being honest means being truthful and forthcoming. Honesty is a value that is valued in most societies, while evasiveness can be seen as suspicious. Therefore, option B, "honest," is the correct answer.
