Correct Option (a) Reason : Thermophiles live in very hot places, with temperature ranging from 600-80°C. Many thermophiles (some eubacteria and archaebacteria) are autotrophs and have metabolisms based on sulphur.
Some thermophilic archaebacteria form the basis of food webs around deep-sea thermal vents, where they must withstand extreme temperature and pressures. Archaebacteria can grow in highly acidic (pH = 0.7) and very basic (pH = 11) environments.
