What is your favourite section in a supermarket?
It's the meat section!
it IS the meat section.
Either way is fine, "It's the meat section." or "It is the meat section.".
The contraction, "it's", is the contracted form of "it is".
You may have mistaken "it's" for the possessive form of "it". The possessive form of "it" is actually "its".
I am just telling you that both are correct thats why I commented as
great job , sorry for the misunderstanding
