The answer is the fourth one: Nucleus.

Explanation for each option:

  • Ribosomes: These are found in all cells, both prokaryotic and eukaryotic, as they are essential for protein synthesis.
  • Cytoplasmic membrane: Also known as the cell membrane, this is found in all cells as it defines the boundary of the cell and regulates the movement of substances in and out.
  • DNA: All cells contain DNA as it carries the genetic information necessary for the cell's functions and reproduction.
  • Nucleus: This is not found in all cells. Only eukaryotic cells have a nucleus, which houses their DNA. Prokaryotic cells, such as bacteria, do not have a nucleus; their DNA is located in the nucleoid region.

Summary: The feature not found in all cells is the nucleus.
