A 35-year-old patient with septicemia resulting from perforation of small intestine presented for emergency laparotomy. He received succinylcholine during induction of anesthesia to facilitate endotracheal intubation. Within one minute, ECG monitor revealed tall peaked T waves, absence of P waves and marked prolongation of QRS complexes. Acute hyperkalemia is suspected. The first choice of action in this particular situation is -

• A. Glucose insulin infusion
• B. IV calcium gluconate administration
• C. Cardioversion
