Correct Answer: Of the capillary action phenomenon


Solution : The answer is the capillary action phenomenon .

The capillary action phenomenon causes oil to rise in the lamp's wick. Molecules in this liquid flow through the narrow gaps in a wick without the assistance of an outside force. The intermolecular interactions between solid and liquid molecules facilitate this movement.
