Correct Option (c) Reason : According to 10% law of energy flow by Raynold Lindeman. The total amount of energy that can be transferred to the next trophic level is the 10% hence, peacock will receive 0.02 J of energy as top consumer.
Energy received by other organisms are
Plant → 20 J
Mice → 20 10% = 2 J
Snake 2 x 10% = 0.2 J
