B. Daughter
C. Niece
D. Wife

Explanation

To solve the problem step by step, we will analyze the relationships given in the statements.

### Step 1: Identify the relationships from the first statement.
- **Statement (i):** A is the son of B.
- This means B is a parent of A. We do not know the gender of B yet.

**Hint:** Start by identifying the relationships mentioned in the statements.

### Step 2: Analyze the second statement.
- **Statement (ii):** C, who is the sister of B, has a son D and a daughter E.
- Since C is the sister of B, C is female (represented as -).
- C has a son (D) and a daughter (E). Therefore, D is male (+) and E is female (-).

**Hint:** Look for siblings and their children to establish family connections.

### Step 3: Understand the third statement.
- **Statement (iii):** F is the maternal uncle of D.
- The term "maternal uncle" indicates that F is the brother of D's mother. Since C is D's mother (as C is the sister of B and has D), F must be C's brother.
- Therefore, F is also B's brother.

**Hint:** Maternal uncle means the uncle from the mother's side, which helps identify family ties.

### Step 4: Determine the relationship between E and F.
- Since F is the brother of C (D's mother), and C is E's mother, F is also E's uncle.
- Therefore, E is the niece of F.

**Hint:** Use the family tree structure to visualize the relationships and identify how E is related to F.

### Final Answer:
E is the niece of F.
