Task: Class Definition Understanding (ontology: Sciences/Biology)

Which of the following definitions best describes 'intracellular water homeostasis'?

A. Any process that results in a change in state or activity of a cell (in terms of movement, secretion, enzyme production, gene expression, etc.) as a result of a stimulus reflecting the presence, absence, or concentration of water.
B. A homeostatic process involved in the maintenance of a steady state level of water within a cell.
C. Anatomical structure that has as its parts two or more multi-tissue structures of at least two different types and which through specific morphogenetic processes forms a single distinct structural unit demarcated by bona fide boundaries from other distinct anatomical structures of different types.
D. The progression of a cardiac cushion over time, from its initial formation to the mature structure. The endocardial cushion is a specialized region of mesenchymal cells that will give rise to the heart septa and valves.

Answer: A homeostatic process involved in the maintenance of a steady state level of water within a cell.
