**Core Concept**
Propofol is a short-acting sedative-hypnotic agent commonly used for the induction of general anesthesia. Its pharmacological effects are primarily mediated through the inhibition of GABA reuptake, enhancing the activity of inhibitory neurotransmitters in the central nervous system.

**Why the Correct Answer is Right**
The correct answer is likely related to the vasodilatory effects of propofol. Propofol can cause a decrease in systemic vascular resistance and a subsequent decrease in blood pressure. This is due to its ability to relax vascular smooth muscle and reduce the release of vasoconstrictor substances. As a result, patients undergoing propofol induction may experience hypotension.

**Why Each Wrong Option is Incorrect**
* **Option A:** This option is not directly related to the pharmacological effects of propofol.
* **Option B:** While propofol can cause respiratory depression, this is not the most likely observation during induction.
* **Option C:** This option may be related to the effects of other anesthetics, but not propofol specifically.

**Clinical Pearl / High-Yield Fact**
When administering propofol, it's essential to closely monitor blood pressure and have vasopressors readily available to manage potential hypotension.

**Correct Answer: C. Hypotension.**
