The correct answer highlights the unpredictable nature of combining alcohol with medication. When these two substances are mixed, the interaction can vary significantly based on multiple factors, including the type of medication, the amount of alcohol consumed, and the individual's unique physiology. This unpredictability can lead to enhanced side effects, reduced effectiveness of the medication, or even dangerous reactions that could affect a person’s health and safety.

Looking at the other options, it's important to note that alcohol does not simply get overpowered by medication; rather, they can interact in complex ways. Likewise, there is often not a straightforward cancellation of effects. The combination can amplify certain effects rather than negate them. Lastly, the claim that only medication will show effects overlooks the significant impact that alcohol can have on the body and how it can alter the effects of any concurrently consumed medication.
