Tip-to-tip prehension, often referred to as a precision grip, involves the action of bringing the tip of the thumb in contact with the tip of another finger. This action primarily utilizes the muscles responsible for fine motor movements of the fingers and thumb, including the flexor digitorum profundus (which flexes the distal joints of the fingers), flexor pollicis longus (which flexes the thumb), opponens pollicis (which rotates the thumb), and abductor pollicis brevis (which abducts the thumb). Therefore, both options B and C correctly identify muscle groups involved in tip-to-tip prehension.
