What sea creature can sometimes be microscopic?
Options:
- (A) squids
- (B) a fish
- (C) fungi
- (D) tortoises
- (E) fossils
- (F) barnacles
- (G) bacteria
- (H) alpacas Think carefully first, then make a decision. My thoughts:

Show your work and conclude with the exact phrasing "Therefore, the final answer is [answer]." where [answer] is just the final number or expression that solves the problem.
