Solution

The correct option is A Both Assertion and Reason are correct and Reason is the correct explanation for Assertion.
A cathode ray is a stream of electrons that are seen in vacuum tubes. It is called a "cathode ray" because the electrons are being emitted from the negative charged element in the vacuum tube called the cathode.

Deflection of Cathode Rays by an Electric Field - The application of high voltage to capacitor plates creates an electric field. When a cathode ray is passed through this electric field, the negatively charged electrons are deflected toward the positive charged plate and away from the negatively charged plate.

Therefore, option A is correct.
