B Kevin went to collect pens and pencils from an elementary school near her house.
Explanation:
A pronoun is a word that is used in place of a noun or a noun phrase. In the second sentence the writer, applied a wrong usage or application of the pronoun her to Kevin who is most likely a boy because boys are known to bear the name Kevin. So, instead of this usage of the pronoun her, the author should have used him. Therefore the correct rendering of this sentence is;
Kevin went to collect pens and pencils from an elementary school near his house.
the begINING of the story could be like my dog is cute but sometimes he is really crazy because he likes to run off and almost get runed over and that is the begINING.
