Answer:

The correct option are a) Meiosis 1 in mother c)Meiosis 1 in father d) Meiosis 2 in father

Explanation:

If a normal haploid sperm fertilizes an egg that has undergone non-disjunction in meiosis 1 than offsprings produced might be having Aaa genotype.

If a normal haploid sperm fertilized an egg that had undergone non-disjunction in meiosis 2 then the chances of the offsprings being formed would be AAa , aaa , Aa , aa , a. Hence, option B is not correct.
