The correct option is B Suckers and hooks
The anterior end of the body of Taenia has a knob like scolex. The scolex has four cup like muscular suckers having radial muscles and at an anterior round prominence, the rostellum has about 22 to 32 curved chitinous hooks in two circles. The scolex with its suckers and hooks is an organ of attachment to the intestinal wall of the host, which works as an organ of adhesion.
