Explanation:
Giving permission
We can use modal verbs 'can' and 'may' (but NOT 'could') to give permission or say that someone has permission. The difference between them is the same as in previous examples: 'may' is a more formal and polite way of saying that, while 'can' is used in formal situations. You can come with us.

Answer:
Asking for permission
Unlike statements, when asking for permission or making a request, we use reverse order , i.e. the modal verb goes before the subject:
Can / Could / May + subject + the verb
Informal
We often use the modal verb ‘can’ to ask for permission or to make a request:
Can I have some cookies? – Yes, you can.
Can I borrow your pen, please? – Sure!
Can I use your bathroom? – Of course!
‘Can‘ is the least formal of these verbs. We use it when we are asking a friend or someone we know for something in an informal situation; or if we are asking someone we don’t know for something which is small or unimportant. For example:
Can I open the window?
Polite
— ‘Could‘ is a little more polite than ‘can’, so we can use it in more formal situations, like talking to your boss or a stranger, or to ask for something more important:
Excuse me, could I sit here, please? – I’m sorry, but you can’t. This seat is taken.
Could I have your attention, sir? – Sure.
Could you tell me the way to the town center, please? – Of course, it’s straight ahead.
— ‘May‘ is similar to ‘could’ but it is even more polite, and also a little old-fashioned, so it is not used as often.
May I make an appointment for Tuesday? – Yes, you may.
May I begin? – Of course.
May I have a glass of water? – Sure, here you are.
Note: Like in examples above, we can give someone permission with the words ‘can’ or ‘may’, or we can say ‘yes’, ‘of course’ or ‘sure.’
