Assertion: The bryophytes are also known as vascular cryptogams.
Reason: Pteridophytes are non vascular plants.

Options

A. If both A and R are true, and R is the correct explanation of A
B. If both A and R are true, but R is not the correct explanation of A
C. If A is true but R is false
D. If both A and R are false

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that "Bryophytes are also known as vascular cryptogams." We need to analyze this statement.
- Bryophytes are a group of plants that include mosses, liverworts, and hornworts. They are characterized by the absence of vascular tissues (xylem and phloem).
- Therefore, the assertion is **incorrect** because bryophytes do not have vascular tissues and are not classified as vascular cryptogams.

2. **Understanding the Reason**: The reason given is "Pteridophytes are non-vascular plants." We need to evaluate this statement as well.
- Pteridophytes, which include ferns and horsetails, are indeed vascular plants. They possess vascular tissues (xylem and phloem) that allow them to transport water and nutrients.
- Hence, the reason is also **incorrect**.

3. **Conclusion**: Since both the assertion and the reason are incorrect, we can conclude that the correct answer is that both the assertion and the reason are false.

4. **Final Answer**: The correct option is **4**: Both A and R are incorrect.
