Explanation

### Step-by-Step Solution:

**Step 1: Understand the Assertion and Reason**
- The assertion states that "Rayon is a semisynthetic polymer and is taken as a better choice than cotton fabric."
- The reason states that "Mechanical and aesthetic properties of cellulose can be improved by acetylation."

**Step 2: Analyze the Assertion**
- Rayon is indeed classified as a semisynthetic polymer. It is derived from natural cellulose, which is obtained from wood pulp.
- The process of making rayon involves chemical treatment of cellulose, making it semisynthetic.
- Rayon is often considered a better choice than cotton fabric due to its improved properties such as softness, luster, and drape.

**Step 3: Analyze the Reason**
- The reason mentions that the mechanical and aesthetic properties of cellulose can be improved by acetylation.
- Acetylation is a chemical reaction where cellulose is treated with acetic anhydride, enhancing its properties. This process results in rayon, which has better qualities than untreated cellulose.

**Step 4: Determine the Relationship Between Assertion and Reason**
- Both the assertion and reason are correct statements.
- The reason explains why rayon is considered a better choice than cotton, as the acetylation process improves the properties of cellulose, leading to the creation of rayon.

**Step 5: Choose the Correct Option**
- Since both the assertion and reason are correct and the reason explains the assertion, the correct option is:
- **Option 2:** Assertion and reason both are correct statements and reason explains the assertion.
