Choose the wrongly matched pair from the following?

Options

A. Auxein - "to grow"
B. Gibberellins - Gibberella fujikuroi
C. Cytokinins - Herring sperm DNA
D. Abscisic acid - Flowering hormone

Answer

To solve the question of identifying the wrongly matched pair of plant hormones and their functions, we can follow these steps:

### Step 1: Understand the Hormones and Their Functions
We need to analyze each hormone mentioned in the options and see if their functions are correctly matched.

### Step 2: Analyze Each Pair
1. **Auxin**: This hormone is indeed responsible for promoting growth, particularly cell elongation. The match is correct.

2. **Zyberlin (Gibberellin)**: This hormone is derived from the fungus Gibberella fujikuroi (previously known as Gibberella fusicariae). It promotes stem elongation, seed germination, and malting. This match is also correct.

3. **Cytokinin**: This hormone is involved in cell division (cytokinesis) and was discovered as kinetin, which is derived from DNA. This match is correct as well.

4. **Abscisic Acid (ABA)**: This hormone is known as a stress hormone and is responsible for processes such as stomatal closure and seed dormancy. This match is also correct.

### Step 3: Identify the Wrong Match
After analyzing all the pairs, we find that all the pairs are correctly matched based on their functions and origins. However, if we are to choose the wrongly matched pair, we need to look for any discrepancies in the description of the hormones or their functions.

### Conclusion
Since all descriptions appear accurate, it seems there may be a misunderstanding in the question or the options provided. However, based on the analysis, the fourth option regarding ABA seems to be the most likely candidate for being wrongly matched if we consider the context of the question.

### Final Answer
The wrongly matched pair is the fourth option related to Abscisic Acid (ABA).
