Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : The CAM plants undergo night time acidification and day time deacidification.
Reason (R) : The CAM plants take up $\text{CO}_2$ during day time, store it in the form of malate in vacuoles and break it down to release $\text{CO}_2$ in the night time.
