I have been asked this question in a national level competition.

I’d like to ask this question from Writing System in section Recording System of Biomedical Instrumentation

Right answer is B. Cathode Ray Oscilloscope

Explanation: Cathode ray oscilloscopes are widely used for the display of waveforms encountered in the medical field. These waveforms can be recorded from the CRO screen by running a photographic film through a recording camera fixed in front of the screen. Recorders are either of the single channel type or of the type which record several channels simultaneously.
