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:

A
Both Statement I and Statement II are true
B
Both Statement I and Statement II are false
C
Statement I is true but Statement II is false
D
