Final answer:
The proper landing technique does not describe any of the given options.
Step-by-step explanation:
The correct answer is option d) None of the above. Proper landing technique in activities such as jumping and landing requires specific alignment and positioning of various body parts to prevent injuries.
Option a) describes a prone position, which is lying face down with limbs touching at the sides. Option b) describes a standing position with upper limbs extended and lower limbs in a wide stance. Option c) describes a supine position with limbs touching at the sides.
In proper landing technique, the knee should be positioned in line with the foot to prevent excessive stress on the knee joint. The feet should be shoulder width apart to provide a stable base of support. There should be no valgus motion of the knee, which is a medial collapse of the knee inward. The shoulders should be positioned behind the knees to maintain proper body alignment.
