Leaf beetles (Chrysomelidae) have eyes that are which of the following?

Explanation:
Leaf beetles have compound eyes on the sides of the head, and in this family those eyes are typically oval-shaped. This shape is a common, recognizable trait for members of Chrysomelidae and fits with how their heads sit relative to the rest of the body. The other statements aren’t reliable traits for the group: antennae length varies and isn’t fixed at half the body length, the head is not consistently narrower than the pronotum, and while some species may be wingless, leaf beetles are generally winged and rely on their wings for dispersal. So the oval eyes best describe their typical appearance.
