The correct answer is: D. Bees wax and paraffin wax
Paraffin wax is a white or colorless solid derived from petroleum. It is a mixture of long-chain hydrocarbons that are solid at room temperature. Beeswax is a yellow or white solid derived from the honeycomb of honey bees. It is a mixture of long-chain hydrocarbons and esters.
Candle wax is a mixture of paraffin wax and beeswax. The paraffin wax provides the candle with its shape and structure, while the beeswax helps to make the candle burn more slowly and evenly.
The other options are incorrect because they do not include both paraffin wax and beeswax. Option A, paraffin wax and stearic acid, is incorrect because stearic acid is a type of fatty acid, not a type of wax. Option B, bees wax and stearic acid, is incorrect because stearic acid is not a major component of beeswax. Option C, higher fatty acids and stearic acid, is incorrect because higher fatty acids are not a major component of candle wax.
