The process that removes apical dominance is ?

Options

A. Removal of shoot tips
B. Provide plants with a lot of auxin
C. Both (a) and (b)
D. None of these

Answer

To solve the question regarding the process that removes apical dominance, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Apical Dominance**:
- Apical dominance is a phenomenon in plants where the growth of lateral buds is inhibited by the presence of the apical bud. This is primarily due to the production of auxins, which are plant hormones released by the apical bud.

2. **Identifying the Options**:
- The options provided are:
a) Removal of shoot tips
b) Provide plants with a lot of oxygen
c) Both A and B
d) None of these

3. **Analyzing Each Option**:
- **Option A (Removal of shoot tips)**: This option suggests that by removing the apical bud (or shoot tip), the inhibition on lateral buds is lifted, allowing them to grow. This is a known method to promote bushy growth in plants.
- **Option B (Provide plants with a lot of oxygen)**: This option does not directly relate to apical dominance. Providing oxygen does not affect the growth regulation caused by auxins.
- **Option C (Both A and B)**: Since Option B is incorrect, this option cannot be correct.
- **Option D (None of these)**: This is also incorrect because we have identified a valid process in Option A.

4. **Conclusion**:
- The correct answer is **Option A: Removal of shoot tips**. This action effectively removes the source of auxins that inhibit lateral bud growth, thus allowing the lateral buds to sprout and grow.

### Final Answer:
The process that removes apical dominance is **removal of shoot tips**.
