What method of thermal energy is used when ice is melting? conduction, convection, our radiation?

Radiation is the method of transfer of energy for the melting of ice.

Explanation:Conduction is the transfer of heat energy from one part of matter to other part by atomic collision.While convection is the transfer of heat by the movement of liquid or hot air.And radiation is the way of absorbing or transmitting energy.Hence in ice melting, thermal energy is absorbed so the correct answer is option C which is radiation.
