Answer:
Randomized control trial
Step-by-step explanation:
In simple words, A randomised controlled trial (RCT) is a form of academic study or intervention research that tries to eliminate some forms of prejudice when assessing the efficacy of novel therapies by arbitrarily assigning people to two or more subgroups administering them differentially, and then evaluating their responses.
Thus, from the above we can conclude that the correct answer is randomized control trial.
