The Correct answer is (D)
(1/4)Microbial Fuel Cells (MFCs) are devices that use bacteria as the catalysts to oxidize organic and inorganic matter and generate current.
(1/4)Microbial Fuel Cells (MFCs) are devices that use bacteria as the catalysts to oxidize organic and inorganic matter and generate current.
(2/4)Electrons produced by the bacteria from these substrates are transferred to the anode (negative terminal) and flow to the cathode (positive terminal). Hence, statements 1 and 2 are correct.
(3/4)Microbes are found in great numbers in sewage, and the conditions of a waste water treatment plant are ideal for the types of bacteria that can be used in an MFC.
(4/4)Thus, they can be installed in waste water treatment plants to cleanse water and produce electricity. Hence, statement 3 is correct.
Therefore, option (d) is the correct answer.
Therefore, option (d) is the correct answer.
