Consider the formula P= H *d over M, where • P represents productivity of a camel. • H represents the area of a hump and is measured in square meters (mº), • d represents distance a camel can travel, and is measured in meters (m), and • m represents the mass a camel can carry, and is measured in kilograms (kg). Select an appropriate measurement unit for productivity of a camel. A. M over kg B. kg over m C. kg^3 over m D. M^3 over kg
