 Answer:
A double blind experiment
Explanation:
A double-blind experiment refers to an experiment in which the information about the treatment of the studied variable is provided to neither the researcher nor the participant. In this type of experiment, both the participant and the experimenter are unaware that which participant has got the experimental treatment.
This test is used by the drug researcher in which the placebo treatment along with experimental treatment is provided.  This experiment is performed to ensure that the results are unbiased and the chances of errors and prediction get reduced.
Thus, A double-blind experiment is correct.
