Explanation:
A placebo effect is when a person's physical or mental health appears to improve after taking a placebo or 'dummy' treatment.
In research and psychology, the placebo effect refers to what happens when people experience benefits in their life after being treated with something that has no real medical effect (something that does not work).
In this example, in a study to determine the effect of caffeine on memory, participants received a caffeine pill or a sugar pill. Sugar is an ingredient that has no real medical effects when it comes to memory and does not contain caffeine.
In other words, something that does not work. However, participants who received this treatment had a slight increase in memory.
The participants benefit after taking an inactive substance (sugar pill), which may be due to the placebo effect.
Thus, the correct statement is Option C. The placebo effect.
