Which structure in the gills of a fish increases the surface area?

Correct answer: D. lamellae. Their shape and staggered arrangement gives them a large surface area. C is incorrect because alveoli are located in the lungs, not gills. A is false because microvilli are small projections found on the surface of some cells.
