The correct answer is A, third person omniscient.
A third person omniscient is when the narrator sees and describes different characters points of view. The word omniscient means to have unlimited knowledge.
A second person is when the narrator uses "you" in their story, as in "you, reading this story". This is a very uncommon point of view.
A first person is when the narrator tells about their personal story, using the personal pronoun "I". They only know what they're told by other characters and we only get to see their point of view in the story.
A third person is when the narrator uses "he/she". The reader only knows what the narrator knows. The third person is very similar to the first person, but using the pronouns "he/she".
