The answer is the second one (or B): Abduction-lifting the arm out to the side of the body so that it is parallel to the ground.

Explanation for each option:

  1. Extension - bending the leg at the knee to bring the heel closer to the buttocks:

    • Incorrect. Extension refers to increasing the angle between two body parts, such as straightening a bent knee. The described action is actually flexion.
  2. Abduction - lifting the arm out to the side of the body so that it is parallel to the ground:

    • Correct. Abduction is the movement of a limb away from the midline of the body. Lifting the arm out to the side fits this definition.
  3. Adduction - moving the arm forward so it is in front of the body:

    • Incorrect. Adduction refers to moving a limb toward the midline of the body. Moving the arm forward is actually flexion.
  4. Flexion - bringing the arm from overhead back down to the side of the body:

    • Incorrect. Flexion refers to decreasing the angle between two body parts, such as bending the elbow. Bringing the arm down from overhead is more accurately described as extension or adduction, depending on the context.

Summary: The correct pairing is Abduction - lifting the arm out to the side of the body so that it is parallel to the ground.
