Answer:
C. The war is ruthless and took away the things most important to the identity and happiness of both men.
Step-by-step explanation:
Irony is when an expression means another thing, though, at times, it is used more for humor and empathy. In simple words, irony is the use of language to mean something quite the opposite.
In the given excerpt from Ernest Hemingway's In Another Country, the doctor's question of what they liked to do best before their handicapped condition helped the men remember what they liked. They did not like the war and no one wants to be handicapped 'intentionally'. So, it is ironic that the war took away the very thing they liked doing the most. And that source of happiness and identity was easily taken away from them by the war.
Thus, the correct answer is option C.
