Choose the correct option. A. (__i) is used to initiate flowering and for synchronising fruit set in pineapples B. (__ii) is also known as stress hormone. C. (__iii) is used to induce early seed production in conifers and for increasing sugar yield in sugarcane

Options

A. (i) Ethylene, (iii) Auxin
B. (ii) Ethylene, (iii) Cytokinin
C. (ii) ABA, (iii) GA
D. (ii) GA, (iii) ABA

Answer

To solve the question, we need to identify the correct hormones that match the descriptions provided in the statements A, B, and C.

### Step-by-Step Solution:

1. **Identify the hormone for statement A**:
- The statement mentions a hormone that is used to initiate flowering and synchronize fruit set in pineapples.
- The correct hormone for this function is **Abscisic Acid (ABA)**. ABA is known to play a role in the flowering process and can help synchronize fruit set in certain plants, including pineapples.

2. **Identify the hormone for statement B**:
- The statement refers to a hormone that is also known as the "stress hormone."
- The correct hormone here is **Abscisic Acid (ABA)** as well. It is often referred to as the stress hormone because it helps plants respond to stress conditions such as drought and salinity.

3. **Identify the hormone for statement C**:
- The statement indicates a hormone that is used to induce early seed production in conifers and increase sugar yield in sugarcane.
- The correct hormone for this function is **Gibberellic Acid (GA)**. Gibberellic Acid promotes growth and development, leading to earlier seed production and increased sugar yield in sugarcane.

4. **Compile the answers**:
- For statement A: **Abscisic Acid (ABA)**
- For statement B: **Abscisic Acid (ABA)**
- For statement C: **Gibberellic Acid (GA)**

5. **Choose the correct option**:
- Based on the answers, we can summarize that:
- A: ABA
- B: ABA
- C: GA
- The correct option that matches these answers is the one that lists ABA for the first two statements and GA for the third.

### Final Answer:
The correct option is: **(A) Abscisic Acid, (B) Abscisic Acid, (C) Gibberellic Acid.**
