The correct answer is option (D):
No change
The sentence "Only a coward will give in" uses the phrasal verb "give in." To understand why "No change" is the correct answer, let's analyze the meaning of "give in" and the other options provided.
"Give in" means to yield to pressure or demand, to surrender, or to stop resisting. In the context of the sentence, it implies that only someone lacking courage would surrender or stop resisting. This meaning is perfectly appropriate and makes logical sense.
Now let's consider the other options:
"Give out" has several meanings, but none fit the context here. "Give out" can mean to distribute or to become exhausted. For example, "The teacher gave out the papers" or "My energy is giving out." Neither of these meanings applies to the idea of yielding to pressure.
"Give for" is not a standard idiomatic phrasal verb in English in this context. While you might "give something for a cause," it doesn't convey the meaning of yielding.
"Give away" can mean to donate something, to reveal a secret, or to surrender a lead in a game. For instance, "She gave away her old clothes" or "He gave away the surprise." Again, none of these meanings align with the concept of yielding or surrendering to pressure in a way that would be characteristic of a coward.
Since "give in" accurately and idiomatically expresses the intended meaning of yielding to pressure or demand, and the other options do not, the original underlined part is correct. Therefore, "No change" is the right choice.
