    Actually, none of those choices are correct. You get back 50 random GUID values.

    1. NEWID() returns a random GUID (aka uniqueidentifier)

    2. Select statement has no order by clause, so the results are random.

    3. The GO 50 repeats that batch 50 times (if in SSMS and the batch separator is set to "GO")

    The answer annotated as correct ("50") is not correct... the results are 50 random GUID values. "50" is not returned. Now, if it was a select count(*), that would be different.
