Which option is used by -F to check popular ports?

Explanation:
Using -F activates fast mode, which limits the scan to the 100 most commonly used ports by consulting a predefined port list. This makes the scan much quicker because you’re not probing all 65,535 ports, just the top ones that are most likely to reveal services. It’s not disabling scanning, not a stealth scan, and not checking every port, which is why focusing on “the 100 most popular ports” is correct.
