Hey there! Hello!
For this question, I agree that it's A. It seems to make the most sense, as you are reading how they will use your information and what they're entitled to do with it. But, it never hurts to get a bit more info about the choices on a question!
For B, you're literally just clicking the "I Agree With Terms And Conditions" box without actually reading the terms and conditions. This may lead to your information being shared with other providers, especially email/phone, so that they can send you offers and stuff, among other things, to your spam folder. It's always advisable to at least brush up on a website's terms before giving anyone your primary email address/phone number or any other personal information that you wouldn't give to spammers directly.
C doesn't even make any sense. The child that you tell probably won't know or care about what you're talking about. It's much better to tell an adult that you'll be using the website, not someone who's younger than you and most likely has less experience??
D isn't very good either, since you can still enter information into some website, as long as the website isn't blocked by your school's server.
It probably wasn't necessary, but I hope this helped you out! Feel free to ask me any additional questions if you have any. :-)
