which of the following is a limitation of a clinical trial? a. number of test tubes b. hospital costs c. amount of peer review d. amount of random assignment

The most appropriate answer option is C. amount of peer review.

Explanation:

Clinical trial is a type of detailed study or research that is done for a certain test or treatment given to people about how safe and successful that treatment is.

For a clinical trial, the amount of peer review can prove to be a limitation as the trials mostly do not provide appropriate answers to the questions that are asked by the people from the same field.
