    D. Four

    Step-by-step explanation:

    The number of attributes for the Employee relation is four namely: EmpID, Name, Dept, Salary.

    We said four because it is only four attributes that are defined for the Employee relation, but an instance of the relation can have lesser than four attribute but not more than four attribute.
