Solution

The correct option is C Digitizer

Digitizer is a device that changes information into digital form.

Although fundamentally a digitizer is any device that converts analog signals to a digital form, the term is used by many companies to describe much more than just a bare analog-to-digital converter (ADC). ... Digitized signals are stored in onboard memory or transferred to the memory of a host PC.

Digitizers convert analog or physical input into digital images. This makes them related to both scanners and mice, although current digitizers serve completely different roles.

Digitizers carry out important work in computer-aided design, graphics design and engineering. They also help convert hand-drawn images into textures and animation in video games and movie CGI.
