that is the decay of plants, animals and excretory products...
nitrogen, oxygen and preoteins aren't produced after decay...the only possibility is mineral salts...and i think that is the decay product of plants...

Huh? I think you read the wrong question. Please check again
Oops! My bad :p
Its B , As the amount of energy released is low so the energy remaining in the products is high
the chemical path way is different as all the reactions of anaerobic repiration are not same
Carbondioxide is produced sometimes (like in bread making ,not produced in muscles)

Acarbon dioxide
Bexcess ions
C urea
D water
Co2 is excreted by lungs only
Urea & excess ions by kidney only
so it's D water is excreted by all of them
