look at the "Son with CF"
look at his Genetic markers starting with "I"
"I"-----he got (1,2)-- which he recieved one allele from father(1) and one from mother(2)
since the stem is asking for alleles on father chromosome, so that leave us with with choice B and C. Now repeat the same thing as above for next alleles.
"II"-----4,4
"III"----3,3 ( at this point u can decide for choice C, as in choice B it mentions allele III9)
