The correct option is (a) Extracellular ligands

To explain: The extracellular ligands or the cell wall ligands bind to the toxic metals and that helps in bacterial assimilation of metals. Integral proteins, Intercellular ligands or Intracellular ligands do not bind to the toxic metals in the environment nearby, only the Extracellular ligands bind.
