The correct answer is "abducting; adducting".

Step 1: Understand the question. The question is asking what movements are required to perform jumping jacks.

Step 2: Analyze each option.

• Flexing and extending refer to decreasing or increasing the angle between two body parts, which is not the primary movement in jumping jacks.
• Rotating and circumducting refer to moving a body part in a circle, which is also not the primary movement in jumping jacks.
• Pronating and supinating refer to turning the hand so the palm is facing down or up, which is not relevant to the movement of the lower extremities in jumping jacks.
• Abducting and adducting refer to moving a limb away from or towards the midline of the body, which is the primary movement in jumping jacks.

Step 3: Choose the correct answer. The primary movement in jumping jacks is moving the legs away from and towards the midline of the body, which is referred to as abducting and adducting. Therefore, the correct answer is "abducting; adducting".
