An experiment involving a new pain relief medication involves subjects being randomly assigned to one of two treatment groups. Subjects in one group will take a daily dose of the new medication, and subjects in the other group will take an existing common pain medication. All subjects will check in with a doctor every week to report their symptoms and any side-effects.

What does it mean for this experiment to be double-blind?

(Choice A)
Subjects in both treatment groups are unaware of what is being measured in the experiment.
(Choice B)
Both the subjects and the doctors are unaware of what is being measured in the experiment.
(Choice C)
Both the subjects and the doctors are unaware of who is taking which medication.
(Choice D)
The new and existing medications will both have unpredictable levels of pain relief and side-effects.
(Choice E)
Subjects in both treatment groups are unaware of who is taking which medication.
