The route of administration affects the time to onset of drug effect.

Explanation:
Time to onset is largely determined by how quickly a drug reaches its site of action, which depends on the route of administration. When you give a drug intravenously, it goes straight into the bloodstream, so the effect can begin almost immediately. Intramuscular or subcutaneous administration requires absorption from the tissue, which takes minutes and can vary with blood flow and formulation, delaying onset. Oral administration must dissolve and be absorbed through the GI tract, plus may undergo first-pass metabolism, typically producing a slower onset. Other routes like inhalation can be rapid due to quick absorption in the lungs, but the common thread is that the route influences how fast the drug acts. So the statement is true. The other options don’t fit because they’d deny or limit this general relationship, which pharmacokinetics shows is true for most drugs.
