D is true
B and C are not the exact same, the select statements are different. B is correct
furthermore, the question says where employee id = 123, if you changed “m.employee_id = 123” like mr anonymous suggested, you wouldnt even be querying the data the question is asking for.
None of these are correct. B & C are the exact same.
If you change B to say “WHERE m.employee_id = 123” you would get the correct result.
D
D is the right
