B) H2SO4 (aq) + Ca (OH) 2 (aq) → CaSO4 (aq) + 2 H2O (l)

Explanation:

A is a reaction between a salt FeCl3 and a base KOH

C is a n acid decomposing on it's own to form two products

D is mercury, a metal reacting with oxygen. Two elements reacting. Neither are an acid or a base

E. is an acid reacting with a metal to liberate hydrogen. There is no base
