If in a drug-study to test the effectiveness of a new drug for treating the common cold, you are randomly assigned to a group that gets the drug, this would mean that you

(a) are in the experimental group
(b) are unaware that you are participating in a study
(c) are in the control group
(d) are in the placebo group

this would mean that you(A) are in the experimental group

Explanation:

There are usually two groups in any proper experiment since they want to test the new drug whether it can treat the cold,they will be participants who will be given the drug and those who will not be given the drug.

The group of participants that receive the drug that is being tested is referred to as an experimental group. Those who do not receive the drug may be referred to as a control group. Usually the experimental group is compared to a control group to see what changes does the drug do to an individual who has taken it compared to the ones who hasn't taken it .
