Question

Read the following statements and choose the correct option w.r.t Cornelius van Niel's experiment based on purple and green bacteria.\ (i) He demonstrated that photosynthesis is essentially a light-dependent reaction in which hydrogen from a suitable oxidisable compound reduces carbon dioxide to carbohydrates.\ (ii) In green plants, $\mathrm{H}_{2} \mathrm{O}$ is the hydrogen donor and is oxidised to $\mathrm{O}_{2}$.\ (iii) $\mathrm{H}_{2} \mathrm{~S}$ is the hydrogen donor for purple and green sulphur bacteria and the 'oxidation' product is sulphur or sulphate depending on the organism.\ (iv) The $\mathrm{O}_{2}$ evolved by the green plant comes from $\mathrm{H}_{2} \mathrm{O}$, not from carbon dioxide.\
