What is Narrow AI primarily designed for?

Narrow AI, also known as weak AI, is primarily designed to perform a specific task or a limited range of tasks effectively. This type of artificial intelligence is focused on a singular function or a designated application, such as facial recognition, speech recognition, or playing chess. For example, a facial recognition system is trained specifically to identify and verify individuals based on facial features but does not possess the ability to think or reason beyond that task.

In contrast, options that suggest performing any intellectual task, understanding human emotions, or creating complex algorithms pertain to capabilities beyond the scope of narrow AI and lean towards general AI or even artificial general intelligence, which aims to understand and perform a wide array of cognitive functions. Thus, option A accurately captures the essence of narrow AI's design and functionality, emphasizing its specialization in particular tasks.
