To solve the problem step by step, we need to analyze the relationships given in the question.

### Step 1: Identify the relationships
- X and Y are brothers.
- A is the wife of Y.
- B is the daughter of A.

### Step 2: Establish the family tree
1. Since X and Y are brothers, we can represent them as:
- X (Brother 1)
- Y (Brother 2)

2. A is the wife of Y, so we can add A to the family tree:
- Y (Brother 2) - A (Wife)

3. B is the daughter of A, which means:
- A (Wife) has a daughter B. Therefore, B is the daughter of Y as well (since A is Y's wife).
- Y - A
- B (Daughter of A and Y)

### Step 3: Determine the relationship of B to X
- Since X and Y are brothers, and B is the daughter of Y, it follows that B is the niece of X.

### Conclusion
Thus, the relationship of B to X is that B is X's niece.

### Final Answer
