Solution
The correct option is B Rectrices and remiges Flight feathersare characterized as long, stiff, asymmetrically shaped, but symmetrically paired pennaceousfeathers that can be seen on the wing and tail of a bird. Those on the wings are called remiges, while those on the tail are called rectrices. The primary function of the flight feathers is to aid in the generation of both thrust and lift, thereby enabling flight. Hence, option B is correct.
