Which one of the following is based on convection? (a) Heating of a copper utensil (b) Heating a room by heater (c) Heating of iron rod (d) Heat transferred from sun to earth

Answer: (b). A room heater warms air near it; the hot air rises and cool air sinks, setting up convection currents. Utensil and iron rod heat by conduction; Sun to Earth is radiation. So the answer is (b) heating a room by heater.
