D. III, IV

Answer

**Step-by-Step Solution:**

1. **Understanding Cambium Activity in Winter:**
- In winter, the cambium layer of a plant is less active compared to other seasons. This means that the production of new cells is reduced.

2. **Type of Wood Produced:**
- The cambium produces secondary xylem, which is commonly referred to as wood. During the winter season, the cambium produces fewer secondary xylem elements, resulting in wood that has narrower vessels or lumens.

3. **Naming the Wood:**
- The wood produced during the winter season is known as "late wood" or "autumn wood." It is also referred to as "winter wood." This type of wood is characterized by its darker color.

4. **Final Answer:**
- Therefore, in winter season, cambium is **less active** and produces **late wood**.
