C Correct answer
Explanation

A CRT (Cathode Ray Tube) monitor consists of several key components: the phosphor screen that glows when struck by electrons, the shadow mask that ensures electrons hit the correct phosphor dots, and the electron gun that emits the electron beam. Gas plasma is an entirely different display technology used in flat-panel displays, not in CRT monitors. This is a knowledge-based question about CRT monitor architecture.
