Stage 1: Reflexive crying and vegetative sounds (birth-2 months) corresponds to which option?

Explanation:
The key idea is how infant vocalizations develop in ordered stages. In the very first stage, babies produce reflexive crying and vegetative sounds like cries, fussing, burps, hiccups, and sighs—sounds that are automatic and not used for communication. This matches birth to about two months, so the description fits the initial stage. Later stages involve more voluntary, social, and exploratory sounds (cooing and laughter around 2–4 months, then more varied babbling later), which is why the early reflexive sounds are assigned to the first stage.
