Carboxylation is the most crucial step of the Calvin cycle where CO2 is utilised for the carboxylation of RuBP. This reaction is catalysed by enzyme RuBP carboxylase. Since this enzyme also has an oxygenase activity, RuBisCO has higher affinity for carbon dioxide than oxygen.
Which of the following statements about RuBisCO is true?

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:
