select the correct option w.r.t. Marsilea

Options

A. Heterosporous vascular spermatophyte
B. Heterosporous vascular embryophyte
C. Homosporous vascular crytogam
D. Homosporous non vascular embryophyte

Answer

To solve the question regarding Marsilea, we will analyze the options provided and determine the correct classification based on the characteristics of Marsilea.

### Step-by-Step Solution:

1. **Identify the Classification of Marsilea**:
- Marsilea is classified under the group Pteridophyta, which are vascular plants. This means that it has specialized tissues for conducting water and nutrients.

2. **Determine the Type of Spores**:
- Marsilea is known to produce two types of spores: megaspores (female) and microspores (male). This characteristic indicates that Marsilea is heterosporous, meaning it produces two distinct types of spores.

3. **Analyze the Options**:
- The options provided are:
- A) Heterosporous Vascular Spermatophyte
- B) Vascular Embryophyte
- C) Homosporous Vascular Cryptogram
- D) Homosporous Non-Vascular Embryophyte
- Since Marsilea is heterosporous, we can eliminate options C and D, as they refer to homosporous plants.

4. **Evaluate Remaining Options**:
- Option A refers to "Heterosporous Vascular Spermatophyte". However, Marsilea does not belong to the spermatophytes (seed plants); it is a pteridophyte.
- Option B, "Vascular Embryophyte", is a broader category that includes all vascular plants that have embryos, which applies to Marsilea.

5. **Conclusion**:
- Based on the analysis, the correct option with respect to Marsilea is **B) Vascular Embryophyte**. This option correctly categorizes Marsilea as a vascular plant that produces embryos.

### Final Answer:
**B) Vascular Embryophyte**
