Text Solution

Verified by Experts

The correct Answer is:
B
The phostosynthetic bacteria(e.g. purple non-sulphur bacteria)photosynthesise using bacteriochlorophylls a and b in anoxic envionments,such as the bottom mud of ponds and other stagnant water,although they are able to survive in air.The reducing agent involved is hydrogen rather than water,so oxygen is not produced.Thses bacteria efficiently use infrared light for photosynthesis.
