Explanation

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about a scenario where female flowers are submerged in water and pollen grains are released inside the water. This describes a specific type of pollination.

2. **Identifying the Type of Pollination**: The type of pollination that occurs when pollen grains are released in water is known as "water pollination." More specifically, when the female flowers are submerged, this is referred to as "hypohydrophilic" pollination.
