Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
A photographic film is a strip or sheet of transparent plastic film base coated on one side with a gelatin emulsion containing microscopically small light sensitive silver halide crystals. Thus, it can only be used once as it involves chemical change when a photo is stored in it. On the other hand, video tape is a magnetic tape used for storing video and usually sound in addition. Information on it can be stored in the form of either and analog signal or digital signal which involves a physical change.
