Which feature is listed as Saturniidae's 'reduced mouthparts'?

Explanation:
Saturniidae adults typically have mouthparts that are greatly reduced or even nonfunctional, because these moths do not feed as adults and rely on energy stored during the larval stage. This makes reduced mouthparts a defining, distinguishing feature for the group. The other options describe wing shape, overall size, or leg morphology, which are unrelated to the mouthpart condition, so they don’t reflect the trait of reduced mouthparts.
