Students were given four small bottles marked "A," "B," "C," and "D." They were told that each bottle contained one of the following solutions: HNO₃, NaOH, AgNO₃, and CaCl₂. Their assignment was to identify the contents of each bottle. The students tested a small amount of each solution with a piece of blue litmus paper moistened with distilled water. Only solution B turned the blue litmus paper red. Which solution was in the bottle marked "B"?

• HNO₃

• NaOH
