Answer #1

Option E

First statement is incorrect because sulphur plays an important role in both aerobic and anaerobic metabolism. There are sulphur reducing and sulphur oxidizing bacteria.

Second and third statements are incorrect because sulphur compounds can be used as an electron acceptor as well as electron donor. Sulphur and sulphate are electron acceptor whereas hydrogen sulphide is electron donor.

4th statement is incorrect because sulphur is required by bacteria. Although very high concentration of sulphur Can anybody the growth of bacteria.

Please rate high.
