Answer

To solve the question of selecting the false statement, we will analyze each of the provided statements one by one.

### Step-by-Step Solution:

1. **Statement 1: Scientists who study and contribute to the classification of organisms are known as systematists.**
- This statement is true. Systematists are indeed the scientists who specialize in the classification of organisms.

2. **Statement 2: Carolus Linnaeus developed the first scientific system of naming species.**
- This statement is also true. Carolus Linnaeus is known for creating the binomial nomenclature system, which is the formal system of naming species.

3. **Statement 3: The five kingdom arrangement of organisms was introduced by R.H. Whittaker.**
- This statement is true as well. R.H. Whittaker is credited with proposing the five-kingdom classification system.

4. **Statement 4: Phycomycetes are called clav fungi because of clav-shaped basidia at the end of mycelium.**
- This statement is false. Phycomycetes are not referred to as clav fungi; instead, the term "clav fungi" is associated with the group of fungi that have clavate (club-shaped) structures, which are typically basidiomycetes, not phycomycetes.

### Conclusion:
The false statement is **Statement 4**: "Phycomycetes are called clav fungi because of clav-shaped basidia at the end of mycelium."

### Final Answer:
**Option 4** is the correct answer as it is the false statement.
