Which one of the following is mismatched pair ?

Options

A. a) Largest isolated , single cell - Egg of an ostrich
B. b) Golgi apparatus - Discovered by Altman
C. c) Mitochondria - Name was given by Benda
D. d) Lysosomes - Discovered by de Duve

Explanation

To determine which of the following pairs is mismatched, we will analyze each option provided in the question.

### Step-by-Step Solution:

1. **Option A: Largest isolated single cell is the egg of an ostrich.**
- This statement is true. The ostrich egg is indeed the largest single cell known, making this pair correctly matched.

2. **Option B: Golgi apparatus was discovered by Altman.**
- This statement is false. The Golgi apparatus was discovered by Camillo Golgi in 1898, not by Altman. Therefore, this pair is mismatched.

3. **Option C: Mitochondria name was given by Benda.**
- This statement is true. The name "mitochondria" was indeed given by Carl Benda, making this pair correctly matched.

4. **Option D: Lysosomes were discovered by D Dubey.**
- This statement is true. Lysosomes were discovered by Christian de Duve, and while the name "D Dubey" seems to be a typo or misrepresentation, the concept of lysosomes being discovered by a scientist is correct. However, if we take the name literally, it could be considered mismatched.

### Conclusion:
The mismatched pair is **Option B: Golgi apparatus was discovered by Altman**. The correct scientist who discovered the Golgi apparatus is Camillo Golgi.

### Final Answer:
**Option B** is the mismatched pair.
