Detailed Solution

Concept- Paraffin wax is a white, soft material made up of a mixture of hydrocarbon molecules with 20 to 40 carbon atoms produced from petroleum, coal, or shale oil. Its melting point ranges from 46 to 66 degrees Celsius.
Vaseline is also referred to as petroleum gel. It is mostly made up of mineral oils and paraffin wax, and it is a byproduct of oil production. Vaseline is thus made of paraffin wax.
The melting point of a candle determines the shape of the candle. Container candles in jars, cups, and glasses are made with paraffin with a low melting point. If candles need to stand on their own, such as pillars and other moulded candles, paraffin with a Medium melting point should be used. Option 2 is also correct if the paraffin with a high melting point (more than 150 degrees Fahrenheit) is utilized for more specialised applications such as hurricane candle shells and other candles.
Most lubricating greases are made from paraffin wax, which is only soluble in organic solvents like ether, benzene, and alcohol. Grease is made from paraffin waxes. As a result, this is also the correct option.
Because all three of the above-mentioned choices are correct.
Hence, the correct option is (4).
