D) Diatoms
Cyanobacteria and eubacteria are prokaryotes characterized by the presence of murein (peptidoglycan) which is a repeating framework of long glycan chains having alternate N-acetyl glucosamine and N-acetyl muramic acid; these glycan chains are cross-linked by short peptide fragments to provide a strong but flexible support framework. Nostoc is a genus of cyanobacteria. Diatoms are photosynthetic protist (eukaryotes) having cell wall deposited with silica and other minerals. The correct answer is D.
