A
Water
B

C
Steam
D

Explanation: 

Detailed explanation-1: -Convection is not possible in solids because for convection to take place the molecules of a substance should be free to move like liquids and gases.

Detailed explanation-2: -Convection only happens with fluids, materials that can flow. Liquids can flow (think of water) and gases can flow (think of wind). Solids are stuck in place so they can’t flow and since they can’t flow, there is no convection. The way heat transfers through solids is conduction.

Detailed explanation-3: -conduction – the transfer of energy through a solid or liquid without the. material itself moving. energy transfer – the movement of energy from one place to another. temperature – a measure of the hotness or coldness of an object.
