1. A solution of β-naphthol in dichloromethane
2. An acidic solution of β-naphthol
3. A neutral solution of β-naphthol
4. An alkaline solution of β-naphthol

Correct answer: An alkaline solution of β-naphthol

Solution

The correct answer is An alkaline solution of β-naphthol because the dye test for identifying β-naphthol requires an alkaline solution to produce the characteristic color reaction.
