Since you aren't saying "the officer", it is specifically referring to one officer. Capitalize, officer.
A and D are the only logical answers, I feel like A fits best because B and C don't really fit under being "timely" or "topical." Feasible answers, yes, but they don't fit the best. If A is wrong, I'd say D.
This is false, and the opposite is true!
A want, used as a noun, refers to something that is not necessary, but something that is wanted, desired only.
A need, in contrast, refers to something that is necessary, so it is not merely something that is wanted, but something that is very essential.
C? I believe this is the correct answer
This is the answer i found on a question similar to this. She killed herself because she could bear the burden of what she had done. She had slept with her own son, who also murdered her husband/his father. Also, she had given birth to Oedipus' children. So she then realized her children were the product of incest. She killed herself because she loved both her son and husband dearly and could not bear to face the fact that the prophecy turned out to be true.
Hope this helps.
