Assertion : Agrobacterium tumefaciens is popular in genetic engineering because this bacterium is associated with the roots of all cereal and pulse crops.
Reason : A gene incorporated in the bacterial chromosomal genome gets automatically transferred to the crop with which the bacterium is associated .

Options

A. If both the assertion and the reason are true and the reason is a correct explanation of the assertion.
B. If both the assertion and reason are true but the reason is not a correct explanation of the assetion
C. If the assertion is true but the reason is false
D. If the both the assertion and reason are false

Explanation

To solve the question, we need to analyze both the assertion and the reason provided.

### Step-by-Step Solution:

1. **Understanding the Assertion:**
- The assertion states that "Agrobacterium tumefaciens is popular in genetic engineering because this bacterium is associated with the roots of all cereal and pulse crops."
- **Analysis:** This statement is incorrect. Agrobacterium tumefaciens primarily infects dicotyledonous plants and is not associated with all cereal and pulse crops, which are mostly monocots. Therefore, the assertion is false.

2. **Understanding the Reason:**
- The reason states that "A gene incorporated in the bacterial chromosomal genome gets automatically transferred to the crop with which the bacterium is associated."
- **Analysis:** This statement is also incorrect. While Agrobacterium tumefaciens can transfer genes to plants, the gene of interest is typically introduced via a plasmid (an extrachromosomal DNA), not directly incorporated into the bacterial chromosomal genome. The transfer is not automatic; it requires specific conditions for the gene to be transferred to the plant cells. Therefore, the reason is also false.

3. **Conclusion:**
- Since both the assertion and the reason are false, the correct answer to the question is that both the assertion and the reason are false.

### Final Answer:
Both the assertion and the reason are false.
