Hi there!
This would be an example of an energy pyramid! In an energy pyramid, the next trophic level gets only 10% of the energy from the level below it. In this example, lets say that there is 100 energy in the eggs. Then, 10% of that goes to the snake, so the snake gets 10. Lastly, the hawk eats the snake, so the hawk gets 1. The answer is 1%, option A.
Hope this helps!! :)
If there is anything else that I can help you with, please let me know!
