1. the wrong word is 'is' (option b) because the subject is plural or more than one (all employees) so it should be 'are'.
2. the wrong word is 'visit' (option c) because the subject is singular (one of my..) so it should be 'visits'.
3. the wrong one is 'not' (option b) because you still need an auxiliary verb (do) to make a negative sentence, so it should be 'do not'.
4. the wrong one is 'don't' (option a) because the subject is singular (mary) so it should be 'doesn't'.
