Basophilic prokaryotes (a) grow and multiply in very deep marine sediments (b) occur in water containing high concentrations of barium hydroxide (c) readily grow and divide in sea water enriched in any soluble salt of barium (d) grow slowly in highly alkaline frozen lakes at high altitudes.
Option A Basopilic prokaryotes are facultatively anaerobic bacteria. They grow and multiply in very deep marine sediments. Most basophiles grow better at a pH of 8.5 or higher.
