ANSWER: C. climates.

EXPLANATION: The Köppen Classification System is widely used as a classification system for climates. It is introduced in 1900 by the Russian - German climatologist Wladimir Köppen. Climatologist Rudolf Geiger introduced some changes to the classification system in 1954 and 1961 which is why it is also called the Köppen–Geiger climate classification system.
