**Step-by-Step Solution:**

1. **Understand the Question**: The question asks which statement is NOT a function of the placenta.

- This is also a correct function of the placenta.
- **Option D**: "It secretes estrogen."
- This is a correct function of the placenta as it secretes various hormones, including estrogen.
