Control is the standard by which experimental observations are evaluated. In many clinical trials, one group of patients will be given an experimental drug or treatment, while the control group is given either a standard treatment for the illness or a placebo. If you have worked with clinical trials/observations, you will clearly understand what the 'control' or 'control group' is. If you have not, say what you do know. In most cases, an interviewer will see if you already have clinical trial experience and know where to guide you with a question like this.
