A research specialist for a large seafood company plans to investigate bacterial growth on oysterssubjected to two different storage temperatures, 0and 10 degrees Celsius. There are 18 refrigeratorsavailable for the experiment, six each of three different brands (Brand A, Brand B and Brand C).Each refrigerator has been stocked with a random selection of fresh oysters harvested from the samebody of water. For each brand, the researcher randomly selects three refrigerators to set at 0 degreesCelsius and the other three are set at 10 degrees Celsius. At the end of the storage period, thebacterial count will be determined on all the oysters and the average count for the two temperatureswill be compared within refrigerator brand. For this experiment, identify the blocking factor, if any.(A)There are no blocks in this experiment(B)The type of seafood(C)The temperature level
