D.
A specific day during which zero threats occurred
Suggested answer: B

Explanation:

A zero-day threat is an attack that takes advantage of a security vulnerability that does not have a fix in place. It is referred to as a ''zero-day'' threat because once the flaw is eventually discovered, the developer or organization has ''zero days'' to then come up with a solution. A zero-day threat can compromise a system or network by exploiting the unknown vulnerability, and can cause data loss, unauthorized access, or other damages. Zero-day threats are difficult to detect and prevent, and require advanced security solutions and practices to mitigate them.Reference:
