Given below are two statements:

Statement $I$: In $\mathrm{C}_3$ plants, some $\mathrm{O}_2$ binds to $\mathrm{RuBisCO}$, 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:
