Answer:
A. Hypothyroidism and hyperthyroidism are imbalances of thyroid hormones.
Explanation:
Hypothyroidism is the result of an underactive thyroid gland and causes symptoms such as slowed metabolism, tiredness, and weight gain.
Hyperthyroidism is the result of an overactive thyroid and can cause symptoms such as unexpected weight loss, rapid or irregular heartbeat, sweating, and irritability.
Because both are a result of under/over activity of the thyroid gland both are imbalances of hormones from the thyroid.
