Correct answer: D
In a Cathode Ray Tube, the Control Grid regulates electron beam intensity. It surrounds the cathode and uses a negative voltage to control how many electrons pass through to strike the screen. Adjusting this grid's potential directly modulates brightness without affecting acceleration or focus.
