    Explanation:

    4th statement is correct. Inheritance of colour blindness is an example of criss-cross inheritance i.e.   

    the son can get it from the otherwise normal but carrier mother and a colour blind father can pass it on to his daughter. Thus this trait is passed to son from carrier mother and to daughter from colour blind father
