A karyotype is an organized profile of a person's chromosomes. Two chromosomes specify sex, XX for female and XY for male. The rest are arranged in pairs, numbered 1 through 22, from largest to smallest. This arrangement helps scientists quickly identify chromosomal alterations that may result in a genetic disorder.

<h2>Answer:</h2>
The correct answer is option A which is, "Electrons are re-energized to be used in NADPH production".
<h3>Explanation:</h3>
In photosystem II, light energy is used to split water molecules which release electrons.
These electrons then move to photosystem I to reduce NADP to NADPH.
Hence electrons in photosystem II are ultimately used to produce NADPH and option C is the correct statement.
