1) in metal object heat transfer through the conduction. In vacuum heat transfer through only radiation.

In only gaseous state or in liquid state the heat transfer through convection hence option D is correct

Dallas Hurley · Answer 2

The answer is: Convection occurs in the presence of a liquid or a gas

Explanation:

Convection is a process by which heat is transmitted, either between two liquid or gaseous substances, provided they are at different temperatures.

Heat transfer occurs when there is a temperature gradient between the two bodies that are in direct contact; then, the heat flow flows from the hottest body to the least hot body. Liquids and gases are considered fluids.
