Which Azure cognitive service should the developer use?

Answer options:

A.Face API
B.Computer vision
C.Video Indexer
D.Bing Video Search

Correct Answer: C
Option A is INCORRECT. Face API facilitates searching, identifying, and matching faces in a private repository. These actions could be done for up to 1 million people.
Option B is INCORRECT. Computer vision helps in real-time video analysis, extraction of text automation, but will not be useful for the given scenario.
