I have noticed that some CAPTCHA pages, like Cloudflare’s, simply ask you to check a box to proceed. There is no clicking on traffic lights or entering characters. How does clicking on a check box tell them I am not a robot?

I’m pretty sure it’s just number 2.
A program will click the box and hit submit instantly. Or it’d move in a perfectly straight line to either the centre of each or the edge of each and click as quickly as possible.
Real human movements are not as precise.
Unless you are really good with a mouse .
