@BalarkaSen If you want to get a cohomology ring you'd better take values in rings :o

@MikeMiller ? That's not the value-category of the sheaf.

Are you sure?
I guess your point is you just forget the ring structure when defining cohomology
And remember it when you want to multiply
Usually you have a product map from F and G-valued coho to F otimes G-valued
