Solution

The correct options are
B Water has more kinetic energy initially
D Temperature of oil increases and water decreases
The temperature of water gradually reduces and that of the coconut oil increases. This happens because oil which was initially at lower kinetic energy state absorbs the kinetic energy of water. Thus the increase in kinetic energy if oil makes oil warmer.
