Statement a. Auxins promote apical dominance by suppressing activity of lateral buds.
Statement b. In moricultrue, periodic pruning of shoot tips is done to make Mulberry plants bushy.

Options

A. a and b correct with a being reason for b
B. a is correct, b is wrong
C. a is wrong, b is correct
D. Both a and b correct but a is not reason for b.

Answer

To analyze the statements provided in the question, we will evaluate each statement separately and determine their validity, as well as their relationship to each other.

### Step-by-Step Solution:

1. **Understanding Statement A**:
- Statement A claims that "Auxins promote apical dominance by suppressing the activity of lateral buds."
- **Explanation**: Auxins are plant hormones that are synthesized at the tip of the plant (the apical meristem). They promote the growth of the apical bud while inhibiting the growth of lateral buds. This phenomenon is known as apical dominance, where the main stem grows more vigorously than the side branches due to the presence of auxins.

**Conclusion**: Statement A is **true**.

**Hint**: Remember that auxins are key players in plant growth and are responsible for the dominance of the main shoot over lateral shoots.

2. **Understanding Statement B**:
- Statement B states that "In horticulture, periodic pruning of shoot tips is done to make Mulberry plants bushy."
- **Explanation**: Pruning involves the removal of certain parts of a plant, such as leaves, branches, or buds, to encourage bushier growth. In the case of Mulberry plants, periodic pruning of the shoot tips is indeed performed to stimulate the growth of lateral buds, making the plant bushier.

**Conclusion**: Statement B is also **true**.

**Hint**: Pruning is a common horticultural practice used to control plant shape and encourage denser growth.

3. **Relationship Between Statements A and B**:
- While both statements are true, Statement A explains a physiological process (apical dominance due to auxins), while Statement B describes a horticultural practice (pruning to encourage bushiness).
- Therefore, Statement A is not the reason for Statement B.

**Conclusion**: Both statements A and B are correct, but A does not explain B.

4. **Final Evaluation**:
- The correct answer to the question is that both statements A and B are true, but A is not the reason for B.

### Final Answer:
Both Statement A and Statement B are correct, but A is not the reason for B.
