A. H2O B. Carbon dioxide C.NAPD D.oxygen

Answer 1

I might be a little too late, I apologize, but the answer is

C) NAPD+

Answer 2

Ans.

An electron carrier is defined as a molecule, which is capable of receiving one or more electrons from an electron donating molecule (electron donor). In given figure, molecule NADP (nicotinamide adenine dinucleotide phosphate) is acting as an electron carrier that accepts electrons form chlorophylls and form NADPH.  

Thus, the correct answer is 'option C). NADP.'
