The correct answer is A

Explanation

Beta-blockers, such as propranolol, labetalol, and pindolol, can have membrane stabilizing effects (eg, quinidinelike effects). This property, usually not evident with therapeutic doses, may significantly contribute to toxicity by prolonging QRS duration and impairing cardiac conduction. Seizures are more commonly observed in the drugs with quinidinelike membrane stabilizing effects
