Select the incorrect match from the following.

Options

A. Phycobiont - Algal parthner of Lichen
B. Phycomycetes - Albugo candida
C. Flagellated protozoan - Trypanosoma
D. Archaebacteria - Cyanobacteria

Answer

To solve the question of selecting the incorrect match from the given options, we will analyze each match provided.

### Step-by-Step Solution:

1. **Understanding the Terms:**
- **Phycobiont:** This is the algal partner of lichen.
- **Phycomycetes:** This is a class of fungi, and Albugo candida is a genus of parasitic fungi that infects plants, particularly mustard.
- **Flagellated Protozoan:** This refers to protozoans that have flagella for movement; Trypanosoma is a well-known example of a flagellated protozoan that causes sleeping sickness.
- **Archaebacteria and Cyanobacteria:** Archaebacteria are a group of microorganisms that can survive in extreme environments, while Cyanobacteria are photosynthetic bacteria, often referred to as blue-green algae.

2. **Analyzing Each Match:**
- **Match 1:** Phycobiont - Algal partner of lichen. (Correct)
- **Match 2:** Phycomycetes - Albugo candida. (Correct, as Albugo is a type of phycomycete)
- **Match 3:** Flagellated protozoan - Trypanosoma. (Correct)
- **Match 4:** Archaebacteria - Cyanobacteria. (Incorrect, as Cyanobacteria are not Archaebacteria; they belong to a different group of bacteria)

3. **Conclusion:**
- The incorrect match is **Archaebacteria and Cyanobacteria**. Therefore, the answer is option 4.

### Final Answer:
The incorrect match is **4th option: Archaebacteria - Cyanobacteria.**
