With the help of DNA fingerprinting which can be used to determine paternity. There are three babies (Baby A, Baby B and Baby C) in a maternity ward, and three sets of confused and worried parents. (Father and Mother #1 are a couple, as are Father and Mother #2, and Father and Mother #3.) 
You do each PCR reaction on chromosome 15 and load each one into a separate well of an agarose gel, and then run the gel.
  

Given the data so far, for which of the following statement is correct

#Section 7: Recombinant DNA technology and Other Tools in Biotechnology
  1. Baby A is legitimate child of given parents because it has a band @ n=25 and there is only one set of parents that could have given a chromosome 15 with n=25 to their offspring, couple #3
  2. Baby B is legitimate child of given parents because it has a band @ n=25 and there is only one set of parents that could have given a chromosome 15 with n=30 to their offspring, couple #2
  3. Baby C is legitimate child of given parents because it has a band @ n=30 and there is only one set of parents that could have given a chromosome 15 with n=25 to their offspring, couple #1.
  4. Baby A is legitimate child of given parents because it has a band @ n=35 and there is only one set of parents that could have given a chromosome 15 with n=35 to their offspring, couple #3.

Electrons ejected from chlorophyll travel through a series of electron carriers organized in the “Z Scheme” shows a current version of the Z scheme, in which all the electron carriers known to function in electron flow from H2O to NADP Presented in the following sequence;

a.) P680 reduce by Yz has received electrons from oxidation of water P680→P680*→pheophytinplastoquinones→ cytochrome b6 f complex→ plastocyanin→ in turn reduces (PSI) P700+

b.) P700+→ P700*→ membrane-bound iron–sulfur proteins → A0→ A1 → flavoprotein ferredoxin–NADP reductase (FNR) soluble → ferredoxin(Fd) → NADP+ to NADPH

c.) P700+→ P700*→ A0→ A1→ membrane-bound iron–sulfur proteins→ ferredoxin(Fd)→ soluble flavoprotein ferredoxin–NADP reductase (FNR)→ NADP+ to NADPH

d.) P680 reduce by Yz has received electrons from oxidation of water P680→P680*→ plastoquinonespheophytin → cytochrome b6 f complex→ plastocyanin→ in turn reduces (PSI) P700+
