c. Nondisjunciton of meioisis II of dad

d. Nondisjunction of meiosis I and II in mom and meiosis II in dad

e. Nondisjunction of meiosis I and II in both mom and dad

f. Nondisujunction of meiosis II of mom

g. Nondisjunction of meiosis I and II in dad

Answer 1

• This error or nondisjunction can happen before conception or early in the embryo's development, resulting in one of these forms of triple X syndrome, Nondisjunction in most cases, either the mother's egg cell or the father's sperm cell divides incorrectly, resulting in an extra X chromosome in the child.

Triple X syndrome is not ​​​​​​​​inherited, but usually occurs as an event during the formation of reproductive cells.

So the suitable option will be option { e }. Both of thems chances are there in the process of division of cells in egg and sperm.
