Given below are two statements:
Statement I : In \({C}_{3}\) plants, some \({O}_{2}\) binds to RuBisCO, hence \(C{O}_{2}\) fixation is decreased.
Statement II : In \({C}_{4}\) 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:
