To determine how A is related to D, we can break down the information given in the statements step by step and create a family tree.

### Step 1: Identify the relationships from the statements

1. **A is the son of B**:
- This means B is A's parent.

2. **C is the sister of B**:
- This means B and C are siblings.

3. **C has a son D and a daughter E**:

4. **F is the maternal uncle of D**:
- This means F is the brother of D's mother (C). Since C is B's sister, F must be B's brother as well.

### Step 2: Construct the family tree
