$\begin{array}{cc}\text{Column A}& \text{Column B}\\ \left(a\right)\text{Methane}& \left(i\right)\text{Gaseous fuel}\\ \left(b\right)\text{Ethanol}& \left(ii\right)\text{Future fuel}\\ \left(c\right)\text{Hydrogen gas}& \left(iii\right)\text{Smokeless fuel}\end{array}$

• A. a - i, b - iii, c - ii
• B. a - i, b - ii, c - iii
• C. a - ii, b - iii, c - i
• D. a - iii, b - i, c - ii

Decomposition of industrial and agricultural wastes in the absence of oxygen results in the production of gaseous fuel i.e., methane.
Fermentation of molasses by yeast i.e., saccharomyces leads to the production of a smokeless fuel i.e., ethanol.
Biophotolysis of water releases hydrogen gas which is used by bacteria for photoreduction and is considered to be the 'fuel of future'.
