Choose the INCORRECT statement.

Options

A. All protozoans are heterotrophs
B. All protists are autotrophs
C. Pellicle is present in euglenoids
D. both (B) &(C)

Answer

To solve the question "Choose the INCORRECT statement," we will analyze each of the provided statements one by one.

### Step-by-step Solution:

1. **Analyze the First Statement: "All protozoans are heterotrophs."**
- This statement is **correct**. Protozoans are indeed heterotrophs, meaning they obtain their food by consuming other organisms or organic matter.

2. **Analyze the Second Statement: "All protists are autotrophs."**
- This statement is **incorrect**. While some protists are autotrophs (like algae), many protists are heterotrophs, meaning they obtain energy from consuming other organisms. Therefore, this statement is the one we are looking for.

3. **Analyze the Third Statement: "Pellicle is present in euglenoids."**
- This statement is **correct**. Euglenoids, a group of protists, possess a pellicle, which is a flexible outer covering.

4. **Analyze the Fourth Statement: "Both b and c."**
- Since statement b is incorrect and statement c is correct, this option is also **incorrect** as it suggests that both statements are wrong.

### Conclusion:
The incorrect statement is **option 2: "All protists are autotrophs."**
