Assertion: Bryophytes are best packing material for trans shipment of living materials.
Reason: Bryophytes like Sphagnum have high shock absorption ability and hygroscopic nature.

Options

A. If both assertion and Reason are true and the reason is a correct explanation of the assertion.
B. If both Assertion and Reason are true but Reason is not a correct explanation of the Assertion.
C. If Assertion is True but the Reason is False.
D. If both Assertion and Reason are False.

Answer

To analyze the assertion and reason provided in the question, we can break down the solution into the following steps:

### Step 1: Understand the Assertion
The assertion states that "Bryophytes are the best packing material for transshipment of living materials." This implies that bryophytes, particularly certain types, are effective for packaging living organisms during transport.

**Hint:** Consider the properties of bryophytes that might make them suitable for packing materials.

### Step 2: Understand the Reason
The reason given is that "Bryophytes like Sphagnum have high shock absorption ability and hygroscopic nature." This means that Sphagnum moss can absorb moisture and cushion the materials it surrounds, which is beneficial for transporting living materials.

**Hint:** Think about how shock absorption and moisture retention can help protect living materials during transport.

### Step 3: Evaluate the Truth of the Assertion
Bryophytes, especially Sphagnum, are indeed used in various applications, including as packing material for plants and seedlings. Their ability to retain moisture and provide cushioning makes them a practical choice.

**Hint:** Reflect on the practical applications of Sphagnum in horticulture and transportation.

### Step 4: Evaluate the Truth of the Reason
The reason accurately describes the properties of Sphagnum moss. Its high shock absorption ability and hygroscopic nature contribute to its effectiveness as a packing material.

**Hint:** Consider how these properties of Sphagnum directly relate to the assertion about bryophytes.

### Step 5: Determine the Relationship Between Assertion and Reason
Since both the assertion and the reason are true, and the reason provides a correct explanation for the assertion, we conclude that the assertion is supported by the reason.

**Hint:** Analyze how the reason justifies the assertion.

### Final Conclusion
Both the assertion and reason are true, and the reason is a correct explanation of the assertion. Therefore, the answer to the question is that both the assertion and reason are true, and the reason explains the assertion.

**Final Answer:** Option 1: Both assertion and reason are true, and the reason is the correct explanation of the assertion.
