Answer: (B)

Verified step by step guidance

1. Understand the components of the cell's internal environment. The cell contains organelles suspended in a fluid medium.
2. Differentiate between the terms: Cytoplasm refers to everything inside the cell membrane excluding the nucleus, including organelles and the fluid.
3. Recognize that the liquid portion of the cytoplasm, excluding organelles, is specifically called the cytosol.
4. Note that nucleoplasm is the fluid inside the nucleus, and the extracellular matrix is outside the cell.
5. Therefore, the correct term for the liquid portion of the cell excluding organelles is cytosol.
