It would be, B. Asteroid belt.
Rough er are flattened spaces while smooth er are tubular
rough er have ribosomes attached to its outer surface while smooth er does not
rough er plays a part in protein synthesis, while smooth er synthesises fats and steroids, and also detoxifies harmful substances
<span>The energy is stored in the phosphate bonds</span>
They both have ribosomes, so the answer is B.
