As we have learnt:

  • Diatoms are mostly found in aquatic and moist terrestrial habitats as free-floating forms.
  • The body of diatoms is covered by a transparent siliceous shell called a frustule.
  • The frustule is composed of two valves which fit together like a soapbox. These two valves are epitheca and hypotheca.
  • So their walls are highly resistant and indestructible.
  • Diatoms are microscopic, eukaryotic and unicellular. They can be found in colonies also.

The walls of the diatoms are indestructible. Hence, the correct answer is option a.
