  4. Cattle
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Renewable energy is generally defined as energy that comes from resources which are naturally renewed. The forest is the best source of renewable energy as the trees collect solar energy on a daily basis and convert this energy into their mass through photosynthesis. Such forest can be replenished by planting new trees.
So, the correct answer is 'Forests'
