What does the presence of a camera microphone and screen in a smartphone show?

Answer and explanation

Correct answer: One device can perform both input and output functions

The governing concept is the distinction between input and output functions in a computer system. A camera captures images and a microphone captures sound, so both provide input. The screen presents text, images, and video, so it provides output. Hence option A is correct: one smartphone combines both functions. Options B and C ignore important functions, while D wrongly claims that every component works identically.
