The source of the oxygen released into the air as a product of photosynthesis is C) Water only.
That phase of mitosis is anaphase
Plant A would have one allele from each parent, so the leaf color will be the dominant one.
Plant B would have a more complex percentage for traits. And it'll probably "cancel-out" some alleles only showing the info given in one of them.
