Options

A. Park and Biggins
B. Hatch and Slack
C. Pelletier dn Caventou
D. Blackman

Answer

**Step-by-Step Solution:**

1. **Understanding Quantosomes**: A quantasome is a structural unit involved in photosynthesis, consisting of chlorophyll molecules. It plays a crucial role in the light reactions of photosynthesis.

2. **Composition of Quantosomes**: Each quantasome typically contains about 230 to 250 chlorophyll molecules and around 50 carotenoid molecules. This composition is essential for capturing light energy.

3. **Function of Quantosomes**: Quantosomes are equipped for photochemical reactions, which are vital for converting light energy into chemical energy during photosynthesis.

4. **Discovery of Quantosomes**: The question asks who discovered quantosomes. The correct answer is that they were first identified by Roderick B. Park and Biggins in 1962.

5. **Elimination of Other Options**:
- Hatch and Slack are known for their work on the C4 cycle.
- Pelleter and Kevin are associated with the discovery of strychnine.
- Blackman is recognized for the law of limiting factors in photosynthesis.

6. **Conclusion**: Based on the above information, the correct answer to the question is Roderick B. Park and Biggins.

**Final Answer**: Roderick B. Park and Biggins discovered quantosomes in 1962.
