Actually, *ALL* of these options work fine: outlook.office365.com and smtp.office365.com point to *the same destination*, and the service is available on both port 25 and port 587.
If “legacy” means “unable to authenticate and use TLS”, then things get more tricky and you need to create a receive connector and use your MX record instead of smtp.office365.com.

Massimo,
No, they do not. Outlook.office365.com is used for setting up POP and IMAP
A and D are the correct choices for setting up SMTP. The questions says “LEGACY” so that would most likely be port 25 (the original SMTP port) as opposed to port 587 which supports STARTTLS.
D is correct.

The correct is “A” (Smtp.office365.com and port 587).

Really tough question as we don’t have enough information. I first was tempted by D because port 25 is usually the default SMTP port, and it seems it would make the most sense for a legacy app. But MS recommends using 587 over 25 (even though both should work). Since I think the test will look for a microsoft answer, I am going with A.

Between D & A I think D is better choice because port 587 should only be used for submissions (i.e., mail client to mail server),
port 25 should only be used for relaying (i.e., mail server to mail server communications)
