What is the difference between "verification testing" and "smoke testing"?

A Smoke testing is a quick, preliminary check of whether the most critical functions of a build work, used to decide if further testing is worthwhile; verification testing more broadly checks that a product meets specified requirements B Smoke testing and verification testing are identical with no distinction C Smoke testing requires testing every single feature in exhaustive detail before any other testing can begin D Verification testing can only be performed by burning physical hardware components
