Hint:

False Negatives in spam detection result in spam emails being incorrectly classified as legitimate.

Answer 1

The Correct Option is B

A false negative occurs when the system incorrectly classifies a spam email as legitimate. This failure to detect spam allows unwanted messages into the user's inbox, potentially causing security issues or clutter. Conversely, a false positive occurs when a genuine email is mistakenly identified as spam.
