I believe the answer is B.
An ideal gas is a theoretical gas in which inter molecular forces do not exist among the molecules and the molecules do not occupy any space. A gas that does not obey ideal gas law are described as non ideal in behaviour. Gases that are most susceptible to non ideal behaviour are those that have attractive and repulsive forces among their molecules and whose particles have volume. Gases that exhibit non ideal behaviour has compressiblity factor ratio that deviate from 1.
Also, it is made up of water and contains enzymes, organelles, salts and various organic molecules. Furthermore, cytoplasm functions by supporting and suspending organelles and cellular molecules. However, example of cytoplasm includes: mitochondria, ribosomes while nucleus is an example of non-example of cytoplasm.
