The correct option is 'B'.
Option B, "has never flown" correctly describes the grandfather's past experience with airplanes. It means he has never flown in an airplane before.
Option A, "never flew" is grammatically incorrect, it implies that he never flew in an airplane at any point in his life.
Option C, "never flies" implies that he never flies at all, now or in the past, which may or may not be true.
Option D, "has been flying" implies that he has flown before and he is still flying, which doesn't align with the statement that grandfather has never flown before.
