Solution

The correct option is B Lamarck
Lamarck has suggested the theory of use and disuse of organs. According to this theory, if any organ is used to its maximum optimum levels it's size increases gradually because of it's repeated use. On the contrary, the size of organs that are used goes on reducing considerably. This is because of their constant disuse.
So, if penguin has lost its ability to fly due to disuse of wings, it comes under Lamarck's theory.
