Which one of the following statements is correct

Options

A. The seed iin grasses is not endospermic .
B. Mango is a parthenocarpic fruit
C. A proteinaceous aleurone layer is present iin maize grain.
D. A sterile pistil is called a staminode .

Answer

To determine which statement is correct among the given options, let's analyze each statement step by step.

### Step-by-Step Solution:

1. **Evaluate the First Statement**:
- The statement claims that the seed in grasses is not in the sperming.
- **Analysis**: This is incorrect because the seed in grasses is indeed in the sperming.
- **Conclusion**: This statement is false.

2. **Evaluate the Second Statement**:
- The statement claims that mango is a carcinocarpid fruit.
- **Analysis**: This is also incorrect because mango is classified as a drupe, not a carcinocarpid fruit.
- **Conclusion**: This statement is false.

3. **Evaluate the Third Statement**:
- The statement claims that a proteinaceous layer on neuron (likely a typo for "endosperm") is present in B screen.
- **Analysis**: This statement is correct. The proteinaceous layer, known as the aleurone layer, surrounds the endosperm in seeds.
- **Conclusion**: This statement is true.

4. **Evaluate the Fourth Statement**:
- The statement claims that a sterile pistil is called a stamen.
- **Analysis**: This is incorrect because a stamen is the male reproductive part of a flower, while a pistil is the female reproductive part. A sterile pistil is not referred to as a stamen.
- **Conclusion**: This statement is false.

### Final Conclusion:
- After evaluating all the statements, the only correct statement is the third one: "A proteinaceous layer on neuron is present in B screen."

### Answer:
The correct statement is the third one regarding the proteinaceous layer surrounding the endosperm.
