Hint 2 of 3
She only adds eyes, so the right picture keeps all of those parts unchanged.

Hint 3 of 3
Pick the picture that matches the start exactly and just adds a sensible pair of eyes.
Show solution
Approach: match the unfinished drawing, change only the eyes
  1. Carina's started picture has the round head, two pointed ears and a single downward triangle (the nose); she only adds eyes.
  2. So the finished cat must keep that same head, ears and nose, with a sensible pair of eyes added above the nose.
  3. The picture that keeps the original parts and just adds eyes in the natural place is B.
