The correct option is A Tail
Flight feathers are the long, stiff, asymmetrically shaped, but symmetrically paired feathers on the wings or tail of a bird where those on the wings are called remiges while those on the tail are called rectrices. The quill feathers of the tail are called tail quills or rectrices (singular rectrix). There are 12 such feathers in a pigeon.
Thus, the correct answer is (B), Tail.
