The well-established sequence of early language development in infants starts with Crying from birth, moves to Cooing around 2 to 3 months, then Babbling around 6 months, and finally the first Single Words around 12 months.
This Crying-Cooing-Babbling-Single Word progression is a standard developmental milestone sequence.
That gives the order (B), (A), (C), (D), matching option 2.
