Bronx Zoo Train Stop

Hi,

Which subway station/stations is/are the closest to the Bronx zoo entrances?
I have seen contradicting answers all over the internet from Tremont to West
Farms to Pelham Parkway and would like to know from someone who is familiar with the zoo.
Please help.

I didn't find the right solution from the Internet.
