Solution

The correct option is B solution of $I_{2}$ in aqueous $K I$
Tincture of iodine is an solution of $I_{2}$ in aqueous $K I$ . It is an antiseptic, it is also called weak iodine solution. It is usually 2-7% elemental iodine, along with potassium iodide, dissolved in a mixture of ethanol and water.
