Answer:
The control group is what your compare your results to. If you are testing the effects of some fertilizer on plant growth you would want to know how much the plant might grow without the fertilizer. You want to make sure, however, that the only factor contributing to the difference in growth rates is the use of fertilizer so you want to make everything else (exposure to light, amount of water, etc) the exact same. Therefore the answer is D.

D. In addition, in the majority of tests it is integral that neither the control group nor the people judging the results know whether a participant is from one group or the other. Exceptions to this rule should be rare.
