D. We cannot say anything for sure.
Dear student.
There are two types of genes that control the type of hair type, curly (C) and straight (s).
Curly hair (CC).
Straight hair (ss).
Wavy hair (Cs)
Father (CC) x Mother (ss)
All the offspring in F1 gen will have genotype (Cs)
This means all the offspring will have curly hair, but not same as that of father, as they also have straight gene 's' from the mother. They will get less curly and more wavy hair.
So here option C. Both the son and the daughter will have curly hair is correct.
Regards.
