Final answer:
Increased heart rate is NOT a side effect of beta-blockers.
Step-by-step explanation:
The correct answer is d) Increased heart rate. Increased heart rate is not a side effect of beta-blockers. Beta-blockers are medications that work by blocking the effects of adrenaline on the heart. By blocking the effects of adrenaline, beta-blockers reduce heart rate and blood pressure. Therefore, beta-blockers would not cause an increased heart rate.
