Best Answer Explained in Below-:

The question states: "The accused refused to his crime." To determine the missing word that best fits the context, we must analyze the meaning of the sentence. The term "refused" indicates that the accused is not willing to accept or acknowledge something. In this case, it refers to the act of acknowledging or admitting guilt related to a crime.

Among the provided options:

A) **Defend** implies the accused is trying to protect themselves against allegations, which does not fit the context of refusing an acknowledgment of guilt.
B) **Agree** suggests conformity with a statement, which is the opposite of refusal and thus irrelevant in this scenario.
C) **Confess** means to admit or acknowledge one’s wrongdoing, which directly contradicts the act of refusal outlined in the sentence.
D) **Protest** would imply the accused is denying or arguing against the accusations, but again, this does not accurately capture the essence of "refusal" in the context of admitting guilt.

Given this analysis, **'C: Confess'** is the logical choice. The sentence structure indicates that the refusal pertains to admitting a crime (confession), and thus highlighting the contradiction and tension within the accused's stance.
