✓ Correct answer: B. 2 vials1.2 g equals 1200 mg. Two vials at 600 mg each combine to give exactly 1200 mg.
Why the other options are incorrect:
• 1 vial: One vial provides only 600 mg, which is half the 1.2 g required.
• 3 vials: Three vials provide 1800 mg, significantly more than prescribed.
• 4 vials: Four vials provide 2400 mg, double the prescribed dose.
• 5 vials: Five vials provide 3000 mg, which would be dangerously excessive.
