The presence of leaves reduced to needle-like structures is the characteristic feature of which habitat?

Options

A. Mountains
B. Deserts
C. Tundras
D. Rain forests

Explanation

**Step-by-Step Solution:**

1. **Identify the Key Feature**: The question asks about the characteristic feature of leaves that are reduced to needle-like structures.

2. **Consider the Options**: The options provided are mountains, deserts, tundras, and rainforests. We need to determine which habitat is associated with needle-like leaves.

3. **Understand the Adaptation**: Needle-like leaves are typically found in coniferous trees. These adaptations help the trees survive in cold environments by minimizing water loss.

4. **Link the Adaptation to the Habitat**: Coniferous trees with needle-like leaves are commonly found in mountainous regions where the climate is cold and snowy. Examples include fir and pine trees.

5. **Conclude the Answer**: Based on the understanding that needle-like leaves are an adaptation to cold environments, the correct answer to the question is **mountains**.
