Which of the following pair is correct ?

Options

A. Bakane – Darwin
B. Cousins – Ethylene
C. Skoog – GA
D. Kurosawa – ABA

Answer

To determine which of the following pairs is correct, we need to analyze each pair mentioned in the question:

1. **Bacani** - This refers to a disease known as "banana bunchy top disease" or "police signaling disease." It was discovered by a Japanese researcher named S. Hori. Therefore, if the pair states Bacani and S. Hori, it is correct. However, if it states Bacani and someone else, it is incorrect.

2. **Fusil Ethylene** - Ethylene is a plant hormone involved in various processes, including fruit ripening. It was discovered that ethylene plays a role in the ripening of bananas when they are stored with oranges. The researcher associated with this discovery is H.H. Fusil. If the pair states Fusil and Ethylene, it is correct.

3. **Scoop GA** - GA refers to gibberellin, a plant growth hormone. It was discovered by a researcher named Kurosawa. If the pair states Scoop and GA, it is incorrect because the name "Scoop" does not relate to the discovery of gibberellin.

4. **Kurosawa AV** - This pair is incorrect because Kurosawa is associated with gibberellin (GA) and not with "AV."

5. **ABA** - ABA stands for abscisic acid, another plant growth hormone. It was discovered by F.D. Addycott. If the pair states ABA and F.D. Addycott, it is correct.

After analyzing all pairs, the only correct pair is **Cousin and Ethylene**.

### Step-by-Step Solution:
1. Identify each term in the pairs: Bacani, Fusil, Ethylene, Scoop, GA, Kurosawa, ABA.
2. Research the discoveries associated with each term.
3. Match each term with its correct researcher.
4. Determine which pairs are correct based on the research.
5. Conclude that the only correct pair is **Cousin and Ethylene**.
