Assertion (A): Learning a skill such as dance and music is an acquired trait.
Reason (R): Acquired traits develop in the life time of an individual and do not pass to the progeny.

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

**Step-by-Step Solution:**

1. **Understanding the Assertion (A)**: The assertion states that "Learning a skill such as dance and music is an acquired trait." This means that skills like dance and music are not inherited genetically but are learned through experience and practice.

2. **Understanding the Reason (R)**: The reason provided is "Acquired traits develop in the lifetime of an individual and do not pass to the progeny." This means that traits acquired during an individual's life, such as skills or knowledge, are not passed on to their offspring.

3. **Analyzing the Truth of Assertion (A)**: Since learning a skill such as dance or music occurs after birth and requires practice, it is indeed an acquired trait. Therefore, Assertion (A) is true.

4. **Analyzing the Truth of Reason (R)**: The reason explains that acquired traits develop during an individual's lifetime and do not get passed to the next generation. This is also true because acquired traits are not encoded in the germinal cells (sperm and ova) that contribute to the genetic makeup of offspring.

5. **Determining the Relationship Between A and R**: Both Assertion (A) and Reason (R) are true. Furthermore, Reason (R) correctly explains why Assertion (A) is true, as it clarifies that acquired traits do not pass to progeny because they are not part of the genetic material that is inherited.

6. **Conclusion**: Since both the assertion and the reason are true, and the reason provides a correct explanation for the assertion, we conclude that both A and R are true, and R is the correct explanation of A.

**Final Answer**: Both Assertion (A) and Reason (R) are true, and R is the correct explanation of A.
