Find the odd one out (w.r.t. class) :

Options

A. Albugo
B. Pythium
C. Aspergillus
D. Phytopthora

Answer

To solve the question of finding the odd one out with respect to class, we will follow these steps:

### Step 1: Identify the Classes
First, we need to identify the classes to which each of the given organisms belongs. The options provided are:
1. Euryomycetes
2. Aspergillus
3. Phytophthora

### Step 2: Classify Each Organism
Next, we classify each organism based on their taxonomic classification:
- **Euryomycetes**: This is a class of fungi.
- **Aspergillus**: This is a genus of fungi that belongs to the class Euryomycetes.
- **Phytophthora**: This is a genus of organisms that belongs to the class Oomycetes, which is different from Euryomycetes.

### Step 3: Compare the Classes
Now we compare the classes of each organism:
- Euryomycetes (class)
- Aspergillus (class: Euryomycetes)
- Phytophthora (class: Oomycetes)

### Step 4: Identify the Odd One Out
From the classification, we can see that:
- Euryomycetes and Aspergillus belong to the same class.
- Phytophthora belongs to a different class (Oomycetes).

Thus, the odd one out is **Phytophthora**.

### Final Answer
The odd one out with respect to class is **Phytophthora**.
