Select correct statements for Equisetum.
(i) Has underground stem rhizome.
(ii) Produce microspores and megaspores
(iii) Terrestrial with distinct compact structure of sporophylls
(iv) Aquatic homosporous member

Options

A. I & iii
B. II & III
C. II & IV
D. I & III

Answer

To solve the question regarding the correct statements for Equisetum, we will evaluate each statement one by one.

### Step-by-Step Solution:

1. **Statement (i): Has underground stem rhizome.**
- Equisetum does have an underground part known as a rhizome. This rhizome serves as a storage organ and helps in vegetative reproduction. Therefore, this statement is **correct**.

2. **Statement (ii): Produce microspores and megaspores.**
- Equisetum is not heterosporous; it is homosporous, meaning it produces only one type of spore. Thus, this statement is **incorrect**.

3. **Statement (iii): Terrestrial with distinct compact structure of sporophylls.**
- Equisetum is indeed a terrestrial plant, and it has sporophylls that are compactly arranged into structures called strobili or cones. Therefore, this statement is **correct**.

4. **Statement (iv): Aquatic homosporous member.**
- Equisetum is not aquatic; it is primarily terrestrial. While it is homosporous, the mention of it being aquatic makes this statement **incorrect**.

### Conclusion:
The correct statements for Equisetum are:
- (i) Has underground stem rhizome (Correct)
- (iii) Terrestrial with distinct compact structure of sporophylls (Correct)

Thus, the correct answer includes statements (i) and (iii).

### Final Answer:
The correct statements for Equisetum are (i) and (iii).
