Rh factor was first reported in Rhesus monkey (Macaca rhesus) by Landsteiner and Wiener in 1940. Those having Rh factor are called Rh positive and those who lack Rh factor are called Rh negative. Rh factor is found only in humans and monkeys. This Rh factor is thus named after Rhesus monkey as Rh stands for rhesus protein. This protein is an antigen present on the surface of red blood cells. So, the correct answer is 'Monkey'.
