Whipworm eggs look like a/an ______ under a microscope.

• A. Cone
• B. Rectangle
• C. Circle
• D. Oval

Answer: (D)

Whipworm eggs have a distinctive elongated, barrel-like or lemon-shaped form with a thick shell and two polar plugs at opposite ends. This gives them an oval silhouette rather than a perfect circle. Among the options, oval best captures that elongated, rounded shape with slightly tapered ends. The other shapes don’t fit: a cone would imply a pointed tip, a rectangle would be angular, and a circle would be perfectly round—none of which describe whipworm eggs accurately.
