Know the Answer?

Gabriela Michael · Answer 1

I believe the answer is C.

Step-by-step explanation:

Neither the test subjects nor the scientists know who got which detergent, so it can't be a biased experiment. It is C because, again, both the scientists and the test subjects know which detergent they got, hence the Double Blind situation.
