Task: Instance Description Understanding (ontology: Earth_Environment/SWEET)

Which of the following definitions best describes the instance 'em'?

A. the instance climate classification, also known as the tundra climate classification, is characterizex by warmest month temperatures between 0 - 10 degree C, precipitation exceeds small potential evapotranspiration demand, and has snow cover 8 - 10 months out of the year.
B. the instance climate classification, also known as the polar marine climate classification, is characterized by all months having temperatures above -7 degree C, warmest month above 0 degree C, and annual temperatures less than 17 degree C.
C. the instance climate classification, also known as the Ice Cap climate classification, is characterized by having warmest month temperatures below 0 degrees C and having precipitation exceeding very small potential evapotranspiration (POTET).
D. In mechanics, a state in which the vector sum of all forces, that is, the acceleration vector, is zero. In hydrodynamics, it is usually further required that a steady state exist throughout the atmospheric or fluid model. the instance may be stable or unstable with respect to displacements therefrom. See also hydrostatic the instance, geostrophic the instance, instability. 2. In thermodynamics, any state of a system that would not undergo change if the system were to be isolated.

Answer: the instance climate classification, also known as the polar marine climate classification, is characterized by all months having temperatures above -7 degree C, warmest month above 0 degree C, and annual temperatures less than 17 degree C.
