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

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

A. 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.
B. the instance is most commonly thought of as an aqueous substance that can accept hydrogen ions. [Wikipedia]
C. the instance climate classification is characterized by winter drought, summer's wettest month getting 10 times more precipitation than driest winter month, and the warmest month being above 22 degree C.
D. the instance as a compound which donates a hydrogen ion (H+) to another compound (called a base). [Wikipedia]
