B. She is an engineer
C. She is a student
D. She is a doctor

Explanation

To solve the problem regarding the family relationships and determine the profession of the granddaughter, we can break down the information step by step:

### Step 1: Identify the Members and Their Relationships
1. We have six family members: P, Q, R, S, T, and U.
2. There are two married couples in the family.

### Step 2: Analyze the Given Information
- T is a teacher and is married to a doctor.
- The doctor is the mother of R and U.
- Q is a lawyer and is married to P.
- P has one son and one grandson.
- Among the two married ladies, one is a housewife.
- There is one student and one male engineer in the family.

### Step 3: Establish Relationships
- Since T is married to a doctor (who is the mother of R and U), we can conclude that T is not the mother of R and U. Therefore, the doctor must be T's spouse.
- Q (the lawyer) is married to P. Since P has one son and one grandson, it implies that P must be the father of R or U.
- Since Q is married to P, Q must be the mother of R and U, making Q the housewife.

### Step 4: Determine the Professions
- We have identified:
- T: Teacher
- Doctor: Mother of R and U (not named yet)
- Q: Lawyer (housewife)
- P: Father (not specified)
- R and U: Children of Q and P
- We know there is one student and one male engineer in the family. Since R and U are the children, one of them must be the student and the other must be the engineer.

### Step 5: Identify the Granddaughter
- Since P has one son and one grandson, and Q is a lawyer (housewife), it means:
- R and U are the children of Q and P.
- If one of R or U is the male engineer, the other must be the granddaughter.

### Step 6: Conclusion
- Given the options (lawyer, engineer, student, doctor), the granddaughter must be the student. Therefore, the correct answer is that the granddaughter is a student.

### Final Answer:
The granddaughter of the family is a student.
