The correct sequence of cell organelles during photorespiration is

The correct sequence of cell organelles during photorespiration is
A Chloroplast, vacuole, peroxisome
B Chloroplast, Golgi bodies, mitochondria
C Chloroplast, rough endoplasmic reticulum, dictyosomes
D Chloroplast, mitochondria, peroxisome

Detailed Solution

Photorespiration begins in the chloroplast, where RuBisCO binds $O_2$ and forms phosphoglycolate.
Glycolate is then metabolised in the peroxisome, and glycine is converted to serine in the mitochondria.
So the three organelles involved are the chloroplast, peroxisome and mitochondria; the only option listing these three is the answer.
