Best answer
Right option is (b) prokaryote

The best I can explain: Prokaryotes and Fungal species have been identified to have industrially important enzymes like protease, lipase, cellulase etc. Lactase synthase, arginase can be extracted from animal species. Phytanase is only available in plant species in abundant. Hence phytanase is extracted from plant species.
