Choose the wrong statement from the following.

Options

A. Neurospora is used in the study of biochemical genetics.
B. Morels and truffles are poisonous mushroom which cannot be consumed.
C. Yeast is unicellular and useful economically in fermentation.
D. Penicillium is multicellular and used for the production of antibiotics.

Answer

To solve the question of identifying the wrong statement, we will analyze each of the provided statements step by step.

### Step-by-Step Solution:

1. **Statement Analysis**:
- **Statement 1**: "Neurospora is used in the study of biochemical genetics."
- **Analysis**: This statement is correct. Neurospora is a genus of fungi that is widely used in genetic research due to its haploid life cycle, which allows for easy observation of genetic traits.

2. **Statement 2**: "Morels and truffles are poisonous mushrooms which cannot be consumed."
- **Analysis**: This statement is incorrect. Morels and truffles are actually edible mushrooms and are considered delicacies in many cuisines. They are not poisonous.

3. **Statement 3**: "Yeast is unicellular and useful economically in fermentation."
- **Analysis**: This statement is correct. Yeast, particularly Saccharomyces cerevisiae, is unicellular and is extensively used in fermentation processes to produce alcohol and bread.

4. **Statement 4**: "Penicillin is multicellular and is used for the production of antibiotics."
- **Analysis**: This statement is correct. Penicillin is derived from the Penicillium mold, which is a multicellular organism, and it is widely known for its antibiotic properties.

5. **Conclusion**:
- After analyzing all statements, the only incorrect statement is **Statement 2**: "Morels and truffles are poisonous mushrooms which cannot be consumed." Therefore, the answer to the question is **Statement 2**.

### Final Answer:
The wrong statement is: **Morels and truffles are poisonous mushrooms which cannot be consumed.**
