Vedclass · Answer

(B) Statement $A$ is true because hydrogen is considered a clean and efficient fuel source.Statement $R$ is also true because certain photosynthetic microorganisms,such as cyanobacteria and green algae,can produce hydrogen gas $(H_2)$ through biological processes by capturing solar energy and converting it into chemical energy stored in the bonds of $H_2$.Since the production of hydrogen by these microorganisms is a primary reason why hydrogen is being explored as a sustainable biological fuel,$R$ provides the correct explanation for $A$.
