The question ask only for those employees Who joined in the month of Jan, Feb, March, April, May, Aug from table employee having a field of join_date where as the correct answers tells that "month(dob) in (1,2,3,4,5,8)" will also give the required data which is not correct. (normally "dob" denotes to Date of Birth)

The other answer " datename(m,join_date) like '%a%' " is also not correct as it will not give the list of employees who joined in the month of FEB

Since both " month(dob) in (1,2,3,4,5,8), datename(m,join_date) like '%a%' " answer are not correct, the last answer "Not in List" is the correct answer.

I nee my points.
