D. Euglenophyceae

Answer

To determine which of the following is a form class, we need to analyze the provided options based on the definition of a form class in the context of fungi.

### Step-by-Step Solution:

1. **Understand the Definition of Form Class**:
- A form class refers to a classification of fungi where the sexual mode of reproduction is absent. This is specifically known as "imperfect fungi."

2. **Analyze the Options**:
- **Option 1: Deutromyc**: This is known as the class of imperfect fungi where sexual reproduction is absent. Therefore, this is a form class.
- **Option 2: Besediumyc**: This class includes fungi that can reproduce both sexually and asexually. Thus, it is not a form class.
- **Option 3: Rodofyc**: This refers to red algae (Rhodophyta), which are not fungi and therefore not a form class.
- **Option 4: Lublinoxy**: This is not a recognized fungal class and does not fit the criteria for a form class.

3. **Conclusion**:
- Based on the analysis, the only option that qualifies as a form class is **Option 1: Deutromyc**.

### Final Answer:
- The correct answer is **Option 1: Deutromyc**.
