You can understand this question better if you would list down all of the details that are mentioned. It says here that Q is a doctor, U is a contractor, S is a housewife. You now have two options available. P can either be a student or a nurse. You can now look at the family relations of the different people involved.

It is evident that T is the youngest since Q is his father and S is his grandmother. This means that P is not a student anymore but a nurse. The answer to this question is letter A. You can list down their professions next to their names so that you can understand this further.
