Solution
The correct option is C upwards
Heat is always transferred vertically upwards through convection.
This occurs because medium particles close to a heat source absorb heat from the source and begin to move faster, so they become farther i.e. the medium expands. As a result, the density of medium near the source of heat becomes less i.e. it becomes lighter.
The less dense medium rises up and the dense medium from above moves down to take its place.
Hence, option (c) ‘upwards’ is correct.
