Picking up a pencil demonstrates the ability to use which of the following?
Correct Answer: A
Rationale: Picking up a pencil requires the use of the pincer grasp, which involves the coordination of the thumb and forefinger to hold small objects. The pincer grasp is a fine motor skill essential for tasks that necessitate precision and dexterity. Choices B, C, and D are incorrect. Prehension refers to the act of grasping or holding an object, parachute reflex is a protective response to sudden movement or loss of support, and grasp reflex is an automatic closing of the hand when an object is placed in the palm, none of which specifically relate to the action of picking up a pencil.
