Bats have wings and no feathers. Ostriches and Emus have both feathers and wings, but they can’t fly mainly due to their huge size. Penguins have feathers and flippers (not wings). “A” is incorrect as bats doesn’t have feathers. “B” is incorrect as penguins doesn’t have wings. “C” is incorrect as there are birds that has both feathers and wings. “D” is the correct answer

Ans 43:

Fe facts:1) Ostriches have wings, though it is not used for flying.2) Bats do not have feathers. They have hairs like other mammals.3) Emu has wings and again not used for flying.4) A penguin has feathers.5) Almost all birds have wings and feathers.So, option D is the only one that seems right.
