Complete the analogy.
B. frail
In the analogy "Arrogant is to modest as feeble is to strong," we are comparing opposite traits.
So, just as arrogant contrasts with modest, feeble contrasts with frail, making B. frail the correct answer.
A. vain is incorrect because "vain" refers to someone overly concerned with their appearance or achievements, which does not align with the opposite of "strong."
