Select the odd one w.r.t. basis of classification of kingdom fungi.

Options

A. Formation of fruiting bodies
B. Mode of spore formation
C. Composition of cell wall
D. Morphology of the mycelium

Answer

To solve the question "Select the odd one with respect to basis of classification of kingdom fungi," we will analyze the options provided based on the classification criteria of fungi.

### Step-by-Step Solution:

1. **Understand the Classification of Fungi:**
- The kingdom Fungi is classified based on several criteria, including:
- Formation of fruiting bodies
- Morphology of mycelium
- Mode of spore formation

2. **Examine Each Option:**
- **Option A: Formation of fruiting bodies**
- This is a valid basis for classification as fungi can be classified into groups based on the type of fruiting bodies they produce.

- **Option B: Mode of spore formation**
- This is also a valid basis for classification since fungi can produce different types of spores (e.g., ascospores, zygospores, basidiospores).

- **Option C: Composition of cell wall**
- All fungi have a cell wall made of chitin, which is a common feature across the kingdom. Therefore, this cannot be used as a basis for classification since it does not differentiate between different groups of fungi.

- **Option D: Morphology of mycelium**
- This is another valid basis for classification as fungi can have different types of mycelium (e.g., septate or aseptate).

3. **Identify the Odd One Out:**
- Based on the analysis, Option C (Composition of cell wall) is the odd one out because it does not serve as a basis for classification within the kingdom Fungi, as all fungi share the same cell wall composition.

### Conclusion:
The correct answer is **Option C: Composition of cell wall**.
