Answer

To solve the question "Calyx having fused sepals is called," we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definition of Calyx**:
- The calyx is the outermost whorl of a flower, consisting of sepals that protect the flower bud before it opens.

2. **Identify the Components of Calyx**:
- The individual parts of the calyx are called sepals. These can either be separate (free) or joined together (fused).

3. **Differentiate Between Free and Fused Sepals**:
- When the sepals are free and not fused, it is referred to as "polysapalous."
- When the sepals are fused together, it is referred to as "gamosepalous."

4. **Analyze the Options Given**:
- The options provided are:
- a) Polysepalus
- b) Polypetalus
- c) Gamosepalus
- d) Gamopetalus
- Among these, "gamosepalus" directly refers to the condition of having fused sepals.

5. **Eliminate Incorrect Options**:
- "Polypetalus" and "gamopetalus" relate to the corolla (the petals of the flower) rather than the calyx.
- Therefore, they are not relevant to the question.

6. **Conclude the Answer**:
- Based on the definitions and the analysis of the options, the correct answer to the question is "gamosepalus."

### Final Answer:
Calyx having fused sepals is called **gamosepalus**.
