The face detection service will report an error when there is no face in the test image.
The correct answer is B. FALSE.

Explanation
Option B (FALSE) is correct because face detection services are designed to handle images with no faces gracefully - they return an empty result set or a response indicating zero faces detected, not an error. The distinction between "no result" and "an error" is fundamental: errors indicate something went wrong (invalid input format, service failure, network issues), while an empty detection result is a valid, expected outcome.
Option A (TRUE) is wrong because it conflates a null/empty result with an error condition - this is a common misconception, but returning zero detections is a normal success response, not a failure state.
Memory tip: Think of it like a search engine - searching for something that doesn't exist returns "0 results," not a crash. Similarly, a face detector finding no faces returns "0 faces found," not an error.
