The correct Answer is:
C
Take two identical rods, one is copper and the other is iron. Fix some nails to the rods with the help of wax at equal distances. Heat the two rods with same spirit lamp at one end by holding at the other ends. Now the nails near to the flame fall, first from the copper rod and then from the iron rod. This happens because the conduction of heat in copper is faster than that in iron.
