B Correct answer
Explanation

The Rh (Rhesus) factor in blood was first identified in the Rhesus monkey, Macaca rhesus. The name 'Rh factor' directly comes from this species. Landsteiner and Wiener discovered this blood antigen in 1937 through experiments with Rhesus monkey blood, which is why it carries this name today. Homo sapiens refers to humans, where the factor is medically relevant, but not where it was first identified.
