Answer

### Step-by-Step Solution

1. **Understanding Hail**: Hail is a type of precipitation that forms in thunderstorms. It consists of layers of ice that build up in a specific way.

2. **Composition of Hail**: Hailstones are primarily made of ice. Specifically, they are composed of alternating layers of transparent and translucent ice.

3. **Structure of Hailstones**: Each hailstone consists of multiple layers. These layers can be described as:
- **Transparent Ice**: Clear ice that allows light to pass through.
- **Translucent Ice**: Ice that partially allows light to pass through but is not completely clear.

4. **Thickness of Layers**: The layers of ice in hailstones can vary in thickness, but it is mentioned that they can be around 1 mm thick.

5. **Correct Answer**: Based on the composition and structure of hail, the correct answer to the question "What does hail consist of?" is:
