Answer
Explanation:
Step1: Understand heat - transfer principle
Heat transfer occurs more rapidly with greater surface - area contact.
Step2: Analyze each position
Standing has the least contact area with the floor. Sitting has more contact than standing but less than lying down. Lying flat on the back has a large contact area. Hands and feet touching the floor has a relatively small contact area compared to lying flat on the back.
Answer:
Flat on her back
