Answer 1

The Correct Option is C

Step 1: Microfauna are conventionally defined as organisms roughly under 0.2 mm in size.
Step 2: Squirrels, mice and beetles are all visible, multi-millimetre to centimetre-scale organisms, so they fall under macrofauna.
Step 3: Only Protozoa, being unicellular and microscopic, fit the microfauna category.
\[ \boxed{\text{(D) only}} \]
