Identifying Basic Solutions Without OH: Examining Salts

[Jules18]

How do you know when something forms a basic solution when dissolved in water if it doesn't have an OH?
This is the question I'm looking at:

Which of the following salts forms a basic solution when dissolved in water?

(A) NaCl
(B) (NH4)2SO4
(C) CuSO4
(D) K2CO3
(E) NH4NO3


Thanks ahead of time.
