Correct option (c) 0. 2 J 

 Explanation:

 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 x 10% =2 J

Snake →  2 x 10% = 0.2 J
