Functional kidney of mammals is Metanephros type. The metanephric kidneys are a paired compact organ whose functional units are nephrons. The nephrons filter initial urine from the blood, reabsorbing water and nutrients, and secrete wastes, producing the final urine, which is expelled.

So, the correct answer is 'Metanephros type'.
