Answer: Energy transfer work in a complete vacuum by only Radiation.
Summery: Energy transfer ie. heat transfer doesn't work in Conduction or in convection because there is no air (Vacuum) in space. Energy transfer possible in space which is vacuum by radiation only.
Hence 4th option is correct in given question.
Hope it helps!!

QUESTION 10 Which option given below is wrong Three modes of heat transfer are: conduction, convection, and radiation. In free convection, the Grashof number is not used as a criterion for laminar and turbulent flow. The conduction heat transfer rate unit is W. The Grashof number in free convection plays the same role as the Reynolds number in forced convection.
