Final answer:
A graphics tablet is a light-sensitive stylus connected to a monitor that sends data to the computer when placed on an on-screen location. The correct answer to the question, which describes a light-sensitive stylus used to interact directly with a computer monitor, is a Light Pen.
Step-by-step explanation:
The item described as a light-sensitive stylus connected to the monitor with a cable that sends data from an on-screen location to the computer when placed on the screen is a Light Pen. Light pens were an early form of input device that enabled users to interact directly with what was displayed on the computer monitor. They function by detecting the light emitted from the screen at the point of contact and thus are particularly attuned to the display's pixel changes.
