Verified step by step guidance

Step 1: Begin by understanding the primary functions of skeletal muscle. Skeletal muscles are responsible for movement, maintaining posture, stabilizing joints, and generating heat.

Step 2: Recognize that shivering is a physiological response to cold temperatures. It involves rapid, involuntary contractions of skeletal muscles to generate heat and maintain body temperature.

Step 3: Eliminate the incorrect options by analyzing their relevance to shivering. For example, 'Pumping blood' is primarily the function of cardiac muscle, not skeletal muscle.

Step 4: Consider 'Maintaining posture' and 'Movement of bones.' While skeletal muscles do perform these functions, they are not directly related to the act of shivering.

Step 5: Conclude that the correct function of skeletal muscle in the context of shivering is 'Heat production,' as the rapid contractions generate heat to counteract the cold environment.
