Answer:

A.   Warm air from a heater on the first floor of a house moves to the upper floors.

Explanation:

As we know that in convection mode of heat transfer the thermal energy is transferred from one point to other point which the actual movement of the medium molecules.

When thermal energy is given to the medium particles then due to difference in the density medium molecules will move from one point to other point along with the thermal energy.

So here we can say that correct answer will be

A.Warm air from a heater on the first floor of a house moves to the upper floors.
