Correct Answer is A

Explanation

A. Crystal violet, iodine, alcohol, safranin: Crystal violet is applied first (primary dye), iodine acts as a mordant to form a dye–iodine complex, alcohol decolorizes, and safranin is the counterstain.
B. Crystal violet, alcohol, safranin, iodine: Iodine must be applied before alcohol to form the mordant complex; this order places the mordant last.
C. Iodine, alcohol, safranin, crystal violet: The primary dye (crystal violet) should be applied first; this sequence starts with the mordant instead.
D. Crystal violet, safranin, alcohol, iodine: Safranin is the counterstain and is applied after decolorization, not immediately after the primary dye.
