how is third-person limited point of view different from third-person omniscient point of view

A) third-person limited POV limits what the reader knows to the thoughts and feelings of only one character

B) third-person POV limits what one of the characters knows by revealing the thoughts and feeling of all the characters

C) third-person limited point of view limits the narration to using only such pronouns as I and we

Im 99% sure it's A but I want to be 100% sure :)
