Answer 1

The correct option is A

It doesn't follow the criss cross pattern of inheritance

Hemophilia follows criss cross pattern of transmission. It is transmission of gene from mother to son or father to daughter. Those patterns of inheritance are called criss cross inheritance or skip generation inheritance, in which a character is inherited to the second generation through the carrier of first generation.
