It certainly is, but once again, the question does not specify enough information to choose an answer. Maybe A is correct, if you have a backup/secondary email to try. Maybe, like so many of us who work with email notifications, they can see the email wasn't opened. Or it bounced. Or it was opened and flagged as spam.
Is that all the information you have? You emailed 120 of them and received 90 clickthroughs? Well sir, that is an astounding clickthrough rate! Perhaps that exceeds every expectation of responses and is itself actionable. Perhaps the best plan of action for the University is to discover their magic clickthrough sauce and monetize it.
What is the best plan of action? Impossible to answer when they haven't specified a goal.
But it IS a multiple choice question, and it is ambiguous, which is why it's not a fine question. It's a sloppy, poorly constructed question, which isn't even enumerated correctly, allowing the instructor to select the "correct" answer based on unspecified reasoning, potentially discriminating against the person answering the question (which I suspect is the intention).
You keep saying this, but the screenshot shows that the student has used an elimination tool (the X on the left) to eliminate one of the possible answers (C).

The question looks like it's from albert.io, so the answer is predetermined (and generally provided by the vendor).
