Assertion: Gene gun method is a direct gene transfer method.
Reason :In this method forgein gene directly introduce in target cell without involving vector DNA

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:

**Step 1: Understand the Assertion**
- The assertion states that the gene gun method is a direct gene transfer method.
- This means that the method involves transferring genetic material directly into the target cells without any intermediary.

**Step 2: Understand the Reason**
- The reason provided states that in this method, a foreign gene is directly introduced into the target cell without involving vector DNA.
- A vector DNA is typically a carrier used to deliver genetic material into a cell. The absence of a vector indicates a direct method of gene transfer.

**Step 3: Analyze the Gene Gun Method**
- The gene gun method, also known as the biolistic method, uses high-velocity microprojectiles (often gold or tungsten particles) coated with DNA.
- These particles are shot into the target cells, allowing the foreign DNA to enter the cells directly.

**Step 4: Evaluate the Truth of the Assertion and Reason**
- Since the gene gun method does indeed transfer genes directly into cells without the use of a vector, both the assertion and the reason are true.
- Additionally, the reason correctly explains why the assertion is true, as it describes the mechanism of the gene gun method.

**Step 5: Conclusion**
- Both the assertion and the reason are true, and the reason is a correct explanation of the assertion.

### Final Answer:
- **Assertion**: True
- **Reason**: True
- **Conclusion**: Both assertion and reason are true, and the reason correctly explains the assertion.
