Identify the correct statement.
(a) Tetrasporic embryo sac occurs in Pepoeromia
(b) Stamens are epipetalous in Grevillea
(c) Cross pollination is Kigellia pinnata takes place by snails
(d) In Scrophularia androecium matures earlier than gynoecium

Options

A. Tetrasporic embryo sac occurs in Pepoeromia
B. Stamens are epipetalous in Grevillea
C. Cross pollination is Kigellia pinnata takes place by snails
D. In Scrophularia androecium matures earlier than gynoecium.

Answer

To solve the question, we need to evaluate each statement provided and determine which one is correct.

### Step-by-Step Solution:

1. **Evaluate Statement (a)**: "Tetrasporic embryo sac occurs in Peperomia."
- In Peperomia, the embryo sac is indeed tetrasporic, which means it develops from four megaspores. This statement is **correct**.

2. **Evaluate Statement (b)**: "Stamens are epipetalous in Grevillea."
- The term "epipetalous" refers to stamens that are attached to the petals. In Grevillea, the stamens are not epipetalous, making this statement **incorrect**.

3. **Evaluate Statement (c)**: "Cross pollination in Kigellia pinnata takes place by snails."
- Cross-pollination in Kigellia pinnata is primarily facilitated by bats, not snails. Therefore, this statement is **incorrect**.

4. **Evaluate Statement (d)**: "In Scrophularia, androecium matures earlier than gynoecium."
- In Scrophularia, both the androecium (male reproductive structure) and gynoecium (female reproductive structure) mature at the same time, indicating that this statement is **incorrect**.

### Conclusion:
The only correct statement among the options provided is:
**(a) Tetrasporic embryo sac occurs in Peperomia.**
