To solve the question "Modified hairy calyx is", we need to analyze the options provided and understand the characteristics of each term in relation to the calyx structure in plants.

### Step-by-step Solution:

1. **Understand the Question**: The question asks for the term that describes a modified hairy calyx. This means we are looking for a specific structure that has these characteristics.

2. **Analyze the Options**:
- **Papus**: This is a structure found in the family Asteraceae (composite family). It is a modified hairy calyx that aids in seed dispersal. It is located below the floret.
- **Perianth**: This term refers to the floral whorl that includes both petals and sepals. If the floral parts are not differentiated, they are collectively referred to as perianth. This does not describe a modified hairy calyx.
- **Epicalyx**: This is a structure that is located outside the calyx. It is not a modified hairy calyx but rather an additional layer.
- **Exericent**: This term describes a condition where the calyx continues to grow after flowering. It is not a type of modified hairy calyx.

3. **Identify the Correct Answer**: Based on the definitions and characteristics analyzed, the correct answer is **Papus**. It is specifically a modified hairy calyx found in the Asteraceae family and is involved in seed dispersal.

4. **Final Answer**: The modified hairy calyx is **Papus** (Option A).
