B. Blinding or masking to prevent bias.

C. Comparable measurement of outcomes in treatment and control conditions .

A randomized controlled trial serves as form of scientific experiment that makes all factors that are not under direct experimental control to be checked.

Some of the components are Rigorous inclusion and exclusion criteria which are needed for the experiments.

Blinding or masking is needed so as to prevent bias and have a genuine result from the experiment.

Therefore, all the given options are right.
