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.
