Assertion: In biolistics method, cells are bombarded with high velocity micr-particles of gold or tungsten coated with DNA
Reason :It is suitable for plant cells

Options

A. If both Assertion & Reason are True & the Reason is a correct explanation of the Assertion
B. It both Assertion & Reason are True but Reason is not a correct explanation of the Assetion
C. If Assertion is True but the Reason is False
D. If both Assertion & Reason are false

Answer

**Step-by-Step Solution:**

1. **Understanding the Assertion**: The assertion states that in the biolistics method, cells are bombarded with high-velocity microparticles of gold or tungsten that are coated with DNA. This is accurate as the biolistic method, also known as the gene gun method, involves using these microparticles to deliver genetic material into cells.

2. **Understanding the Reason**: The reason provided states that this method is suitable for plant cells. This is also correct because the biolistic method is particularly effective for transforming plant cells, which can be challenging to transform using other methods.

3. **Evaluating the Relationship**: To determine if the reason is a correct explanation of the assertion, we need to analyze the connection between the two statements. The assertion describes the method of DNA delivery, while the reason explains the suitability of this method for plant cells. Since the biolistic method is indeed a preferred technique for introducing DNA into plant cells, the reason supports the assertion.

4. **Conclusion**: Both the assertion and the reason are true, and the reason correctly explains the assertion. Therefore, we conclude that the statement is valid.

5. **Final Answer**: The correct option is A: Both assertion and reason are true, and the reason is the correct explanation of the assertion.
