Assertion (A): DNA copying is necessary during reproduction.
Reason ( R): DNA copying leads to the transmission of characters from parents to offspring.

Options

A. Both A and R are true and R is the correct explanation of A.
B. Both A and R are true but R is NOT the correct explanation of A.
C. A is true but R is false.
D. A is false and R is true.

Explanation

To solve the question regarding the assertion and reason, we can break it down into clear steps:

### Step 1: Understand the Assertion
The assertion states that "DNA copying is necessary during reproduction." This means that for reproduction to occur, the genetic material (DNA) must be duplicated.

**Hint:** Think about how organisms pass on their traits to the next generation.

### Step 2: Understand the Reason
The reason states that "DNA copying leads to the transmission of characters from parents to offspring." This implies that through the process of DNA copying, the genetic information that defines traits and characteristics is passed from the parents to their offspring.

**Hint:** Consider how traits like eye color or height are inherited from parents.

### Step 3: Analyze the Relationship
Now, we need to analyze the relationship between the assertion and the reason. The assertion is true because DNA copying is indeed necessary for reproduction. The reason is also true because DNA copying is the mechanism through which genetic traits are transmitted from parents to their offspring.

**Hint:** Reflect on how genetic traits are inherited in living organisms.

### Step 4: Determine the Correct Option
Since both the assertion and the reason are true, and the reason correctly explains why DNA copying is necessary for reproduction, we conclude that the correct option is: "Both A and R are true and R is the correct explanation of A."

**Hint:** Look for options that confirm both statements and their relationship.

### Final Answer
Both A and R are true, and R is the correct explanation of A.
