Correct Answer: Paraffin wax and stearic acid

Solution : The correct option is Paraffin wax and stearic acid.

Paraffin wax and stearic acid are used to make candles. This combination is widely used in the manufacture of candles to attain particular features and characteristics. One of the most common ingredients used to make candles is paraffin wax. It is a petroleum or shale oil-derived hydrocarbon wax. Paraffin wax offers favourable features for candle-making, such as the capacity to maintain scent and colour, the ease with which it may be moulded into candle forms, and its cost. Stearic acid is a saturated fatty acid that is frequently added to candle wax compositions to improve the texture, hardness, and opacity of the candle. It can also assist to decrease leaking and enhance the candle's overall burn quality.
