In C3 plant, some O2 bind to RuBisCO, and hence CO2 fixation is decreased. Statement II is incorrect, photorespiration does not occur in C4 plants as they lack RuBisCO in mesophyll. Hence statement I is the only correct option.
Given below are two statements: Statement I: In C_3 plants, some O_2 binds to RuBisCO, hence CO_2 fixation is decreased. Statement II: In C_4 plants,…
