Answer: not scored. No option is correct as printed.

  1. Lysosomes contain digestive enzymes that break down many biological materials and worn-out cell components.
  2. They do not digest all inorganic material, making (b) too broad.
  3. They also do not prevent foreign material from entering a cell: they can digest suitable material after uptake, so (d) is also false as phrased.
