The correct statement is:

A solution of potassium hydroxide will always have more OH– ions than a solution of ammonia.

This is because potassium hydroxide (KOH) is a strong base that completely dissociates in solution to produce a high concentration of hydroxide ions (OH–). In contrast, ammonia (NH₃) is a weak base that only partially dissociates in solution, resulting in a lower concentration of hydroxide ions compared to an equivalent concentration of KOH.
