All of the answers are wrong. The question is unfair. The security analyst needs to determine if the attachment is safe. Placing the attachment in a malware sandbox, of itself, will not determine anything. Performing a code review of the attachment might determine something. But it is unlikely that the code is available.

You pretty much overthink "most" of the questions asked. I have read some of your answers and you have the same approach "overthinking". even when it is straightforward.

Maybe: B. Perform a code review of the attachment ? It is not likely that any code is available. But, maybe the analyst could de-compile, or search the binary for strings? At least, this might "determine whether or not the attachment is safe." Horrible question. Completely unfair.
