The correct answer is (C) A (long and slender) wax candle; a slender wax-covered wick used for lighting candles; a long wick coated with wax or tallow for use in lighting candles or gas appliances. Also, anything, such as a spire, that has a tapering form.

Taper comes from Old English tapur, tapor, taper.

Examples of use:

• A lit taper simplified the job of lighting the 40 candles on the birthday cake.
• Each singer in the procession carried a lighted taper.
