✓ Answer:
D
C2H5OH
Ethanol (C2H5OH) is not a base, as it does not contribute to increasing the concentration of hydroxide ions in a solution. It is commonly used as a solvent and in alcoholic beverages. Instead, it is a neutral organic compound with no basic characteristics, distinguishing it from KOH, NH4OH, and NaOH, which are all bases.
