Which symptom is typical of hypothyroidism?

• A. Tremors
• B. Weight loss
• C. Rapid heartbeat
• D. Weight gain and cold intolerance

Answer: (D)

When the thyroid is underactive, the body's metabolism slows down, which reduces heat production. That leads to weight gain or difficulty losing weight and feeling unusually cold. Those combined symptoms—weight gain and cold intolerance—are classic signs of hypothyroidism, making this option the best fit.

Tremors, rapid heartbeat, and weight loss are more typical of an overactive thyroid (hyperthyroidism), where metabolism runs fast and symptoms like shakiness, palpitations, and unintended weight loss appear.
