Question
Which statement is not true for protozoans?
Correct Answer
Option A is the correct answer.
Detailed Explanation
Most protozoans are unicellular, meaning they exist as single cells. The statement 'they are rarely unicellular' is therefore incorrect. They are often motile, lack a rigid cell wall, and some can be beneficial while others are pathogenic.
Hint
Focus on the primary cellularity of protozoa.
