Step-by-step explanation:
The correct option is:
a) Onset: Slow, Peak: Rapid, Duration: Short
When a drug is administered intramuscularly, the onset is slow, meaning it takes some time for the drug to start working. The peak of the drug's effect is rapid, meaning it reaches its highest concentration quickly. However, the duration of the drug's effect is short, meaning it doesn't last for a long time.
