Yes, you must first understand how the system works and then solve your question yourself.

Ok so for the first part
Father is O grp & Mother is B grp
case 1 . when Mother is Homozygus (both genes same)
|dw:1334303625795:dw|
O is recessive and can be expressed only in the homozygus condition
so here B is dominant over O
So children can have only B group

well, each parent gives one of the possible blood gropu alleles to the offspring. You know the possibilites are six: AA, AB, AO, BB, BO, OO.
because there are three alleles in human populations.
so one comes from mother and other from father and i saw the drawings of Aadarsh they seem correct.
This is a typical example of polymorphism for the alleles or different versions of a locus or the same: a gene.
