可以
可以(ke3yi3) is a auxiliary verb used to express the meaning “to be permitted” or “can, be able to”. It means that someting is allowed, for example by law, and does not speak about physical ability. It is used in a sentence as follows:
我可以坐这儿吗?- Can I sit here?/ Am I allowed to sit here?
你的房间里有可以上网吗?- Does your room have access to the internet?
In order to answer these question, one uses 可以 in an affirmative answer and 不能/不行 for a negative answer.
Examples:
你可以坐这儿。- You can sit here.
我的房间里可以上网。- My room has accsess to the internet.
你不能坐这儿。- You are not allowed to sit here.
我的房间里不能上网。- My room can not access the internet.
Short versions of these answers coule be just 可以/不能/不行/不可以, used depending on the situation.

A indicates ability, as in mental or physical ability. One has the knowledge to do a thing.
B is used in permissions and for requests.
C is used for possibility
D is used when a permission is not granted
E is used if something is impossible, usually because of a physical component (being sick, e.g.)
