Assertion : Continued self pollination generation after generation results in pure line formation .
Reason : By continued self - pollination plant becomes pure or homozygous for its characters.

Options

A. If both Assertion and Reason are the true and Reason is correct explanation of Assertion .
B. If both Assertion and Reason ar ture but Reason is not correct explanation of Assertion .
C. If Assertion is true but Reason is false .
D. If both Assertion and Reason are false .

Answer

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

### Step 1: Understand the Assertion
The assertion states that "Continued self-pollination generation after generation results in pure line formation." This means that if a plant continues to self-pollinate over multiple generations, it will produce offspring that are genetically uniform or pure.

**Hint:** Think about how self-pollination affects genetic variation in plants.

### Step 2: Understand the Reason
The reason states that "By continued self-pollination, a plant becomes pure or homozygous for its characters." This means that through self-pollination, the plant's genetic makeup becomes more consistent, leading to homozygosity, where both alleles for a trait are the same.

**Hint:** Consider what happens to the genetic makeup of a plant when it self-pollinates repeatedly.

### Step 3: Analyze the Relationship Between Assertion and Reason
Now we need to determine if the reason provided correctly explains the assertion. The assertion is true because self-pollination does lead to pure line formation. The reason is also true because continuous self-pollination does indeed make a plant homozygous for its traits.

**Hint:** Reflect on whether the reason logically supports the assertion.

### Step 4: Determine the Correct Option
Since both the assertion and the reason are true, and the reason correctly explains the assertion, the correct answer would be the first option: "Both assertion and reason are true, and reason is the correct explanation of assertion."

**Hint:** Look for the option that confirms both statements are true and that one explains the other.

### Final Answer
The correct answer is: "Both assertion and reason are true, and reason is the correct explanation of assertion."
