In this question, we need to evaluate the ability to form electrolytes from the given compounds in the question, this is because when a compound is considered to be a strong electrolyte, this means that it will give a lot of ions into the solution and make the solution conduct electricity, so from the given compounds we have:
HCl = is an acid and in a solution it will totally dissociate, being considered a strong electrolyte, therefore it will complete the circuit
Sucrose = is a nonelectrolyte, not dissociating and forming ions, therefore sucrose will not complete the circuit
NaNO3 = same case as HCl, strong electrolyte
(NH4)2SO4 = same case as HCl, strong electrolyte
Answer it will be Sucrose
