I chose B
Red Green Red Red
M shld be plant cell because of chloroplasts which mean in light (B) photosynthesis occurs and CO2 is taken in so low CO2; green
N shld be an animal cell due to lack of chloroplasts which means regardless of light or dark (C and D) , respiration occurs and CO2 is high; red

Now A could be yellow or red but I chose red because in darkness photosynthesis doesn't occur but respiration does. So CO2 shld be high; red
