The answer is the first one: cell.

Explanation for each option:

  • Cell: This is the correct answer. A cell is the smallest unit of life that can function independently. It is the basic structural, functional, and biological unit of all living organisms.
  • Molecule: Molecules are chemical structures consisting of at least two atoms held together by a chemical bond. They are not independently functioning biological units.
  • Organ: An organ is a group of tissues that work together to perform a specific function or group of functions. It is not the smallest unit, as it is composed of multiple cells and tissues.
  • Tissue: Tissues are groups of similar cells that work together to perform a specific function. They are larger than cells and are not the smallest independently functioning units.

In summary, the cell is the smallest independently functioning biological unit of an organism.
