A blood bank receives 450 mL of blood from each donor. After separating blood plasma from red blood cells, the former is stored in bags with 250 mL capacity. The blood bank rents refrigerators from a company for storage of plasma bags, according to its needs. Each refrigerator has a storage capacity of 50 bags. Over the course of a week, 100 people donated blood to that bank. Assume that from every 60 mL of blood, 40 mL of plasma is extracted. The minimum number of freezers that the bank needed to rent to store all the plasma bags from that week was (A) 2. (B) 3. (C) 4. (D) 6. (E) 8.
