Which of the following statements about RuBisCO is true?
Match List I with List II: $\begin{array}{|l|l|l|l|}\hline & \text{List - I} & & \text{List - II} \\\hline \text{A}. & \text{Chlorophyll a} & \text{(i)} & \text{Yellow-green} \\\hline \text{B.} & \text{Chlorophyll b} & \text{(ii)} & \text{Yellow} \\\hline \text{C.} & \text{Xanthophylls} & \text{(iii)} & \text{Blue-green} \\\hline \text{D.} & \text{Carotenoids} & \text{(iv)} & \text{Yellow to Yellow-orange} \\\hline\end{array}$ Choose the option with all correct matches.
Given below are two statements: Statement I: In $\mathrm{C}_3$ plants, some $\mathrm{O}_2$ binds to RuBisCO, hence $\mathrm{CO}_2$ fixation is decreased. Statement II: In $\mathrm{C}_4$ plants, mesophyll cells show very little photorespiration while bundle sheath cells do not show photorespiration. In the light of the above statements, choose the correct answer from the options given below:
