The correct answer is A. became desperate.
The word “amuck” means to run about wildly in a state of uncontrolled anger or excitement. This is consistent with the description of the old beggar in the question, who is said to have “ran amuck
and began to throw stones at the passerby.” This suggests that the beggar was in a state of desperation and was acting out of anger or frustration.The other options are not as consistent with the description of the old beggar. Option B, “ran about wildly,” is too general and does not provide any information about the beggar’s motivation. Option C, “became annoyed,” is also too general and does not provide any information about the beggar’s level of agitation. Option D, “felt disgusted,” is not consistent with the description of the beggar’s actions, which suggest that he was acting out of anger or frustration, not disgust.
