One hormone helps in ripening of fruits and other brings about stomatal closure. They are respectively

Options

A. ABA, IAA
B. `C_(2)H_(4)`, ABA
C. ABA, ethylene
D. `C_(2)H_(2)`, GA

Answer

To answer the question regarding the hormones responsible for fruit ripening and stomatal closure, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Identify the Hormone for Ripening of Fruits**:
- The hormone responsible for the ripening of fruits is **ethylene** (C2H4). Ethylene is a gaseous plant hormone that plays a crucial role in the ripening process of various fruits.

2. **Identify the Hormone for Stomatal Closure**:
- The hormone that brings about stomatal closure is **abscisic acid (ABA)**. ABA is known for its role in plant stress responses and helps in closing the stomata to reduce water loss during drought conditions.

3. **Combine the Information**:
- Therefore, the hormone that helps in ripening of fruits is **ethylene (C2H4)**, and the hormone that brings about stomatal closure is **abscisic acid (ABA)**.

4. **Final Answer**:
- The correct answer to the question is: Ethylene (C2H4) for ripening of fruits and Abscisic Acid (ABA) for stomatal closure.
