Correct answer :
The correct answer is option (b) green plants.
Explanation of Solution
Explanation/justification for the correct answer:

Explanation for incorrect answer :
Option a) foxes. Foxes occupy higher trophic level in the ecology pyramid, hence they have lower biomass.
Option c) mice. Mice also occupy higher trophic level in the ecology pyramid, hence they have lower biomass.
Option d) rabbits. Rabbits occupy second level in the trophic level, hence their biomass is less as compared to green plants.
