Solution
The correct option is D Candle
Ethanol, also called alcohol, ethyl alcohol and grain alcohol, is a clear, colorless liquid and the principle ingredient in alcoholic beverages like beer, wine or brandy. Because it can readily dissolve in water and other organic compounds, ethanol also is an ingredient in a range of products, from personal care and beauty products to paints and varnishes to fuel.
Ethanol is a good solvent and hence is used in many medicines such as tincture of iodine, cough syrup and tonics.
Many cough and cold liquids and other OTC (over-the-counter) products contain some alcohol. In the formulation, alcohol helps to dissolve active ingredients or preserve the product.
Hence,except candle ethanol is used in all above substances therefore option C is correct answer.
