The living content of a cell (protoplasm) is composed of cytoplasm and nucleoplasm.

– Protoplasm refers to all the living substance within a cell membrane.
– In eukaryotic cells, protoplasm includes the cytoplasm (the material within the cell membrane but outside the nucleus) and the nucleoplasm (the substance within the nucleus).
– Cytoplasm itself consists of the cytosol (the jelly-like substance) and the organelles suspended within it. Nucleoplasm contains the genetic material (DNA) and other components of the nucleus.

Option D is redundant because “other organelles” are already included within the definition of cytoplasm. The standard biological definition of protoplasm in a eukaryotic cell is cytoplasm plus nucleus (or cytoplasm and nucleoplasm, which constitutes the living content of the nucleus). Option B accurately reflects this fundamental division within the cell.
