Best answer
Right option is (a) True

Explanation: IF amplifiers are used to change the frequency levels in circuits that are too selective, difficult to tune, and unstable. However, Video amplifier is used to amplify video signals before passing them to a Cathode ray tube. And there is no need of IF amplifier stages for a video monitor.
