Answer: B

Explanation:

A microgram is one millionth of a gram and is abbreviated mcg. It is vital that all people prescribing medicine know the difference between different units, as a mistake can be dangerous or even fatal. For example if a milligram of a drug is administered instead of a microgram the patient will be receiving a dose 1000 times stronger than the one prescribed.
