$ Rhizoids of female gametophyte of selaginella are multicellular.
! Selaginella is homosporous.

Options

A. If both As and R are correct and R is correct explanation of As
B. If both As and R are correct but R is not correct explanation of As
C. If As is correct, R is wrong
D. If both As and R are wrong.

Answer

To solve the question regarding the assertion and reason about Selaginella, we will follow these steps:

### Step 1: Analyze the Assertion
The assertion states that "rhizoids of female gametophyte of Selaginella are multicellular."
- **Fact Check**: In Selaginella, the structures present are not rhizoids but rhizophores. Rhizoids are typically unicellular in many plants, and Selaginella does not have true rhizoids. Therefore, this assertion is incorrect.

### Step 2: Analyze the Reason
The reason states that "Selaginella is homosporous."
- **Fact Check**: Selaginella is actually heterosporous, meaning it produces two different types of spores: megaspores and microspores. Thus, this reason is also incorrect.

### Step 3: Determine the Relationship Between Assertion and Reason
Since both the assertion and the reason are incorrect, we need to evaluate the options provided:
- **Option A**: Both assertion and reason are correct; reason is the correct explanation of assertion. (Incorrect)
- **Option B**: Both assertion and reason are correct. (Incorrect)
- **Option C**: Assertion is correct; reason is incorrect. (Incorrect)
- **Option D**: Both assertion and reason are wrong. (Correct)

### Conclusion
The correct answer is **Option D**, as both the assertion and the reason are incorrect.
