My question is from Controlled Release Medication in portion Controlled Release Medication of Drug Biotechnology

Answer 1

The correct choice is (c) Randomly assigning subjects either for placebo or active dose

To elaborate: Randomized design is when each study subject is randomly assigned to receive either the study treatment or a placebo. The subjects involved in the study do not know which study treatment they receive. If the study is double-blind, the researchers also do not know which treatment is being given to any given subject.
