The correct statement is:

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

Potassium hydroxide (KOH) is a strong base and dissociates completely in solution to produce a higher concentration of hydroxide ions (OH⁻) compared to ammonia (NH₃), which is a weak base and only partially dissociates to produce hydroxide ions. Therefore, KOH will always yield more OH⁻ ions in solution than ammonia.
