The ability to develop language in infants and toddlers involves which of the following?

The development of language in infants and toddlers is a complex process that involves multiple interconnected factors, making the inclusive choice of "all the answers are correct" the most accurate.

Social interaction plays a critical role in language development as infants and toddlers learn to communicate by engaging with caregivers and peers. Through these interactions, they become accustomed to the rhythms and nuances of conversational speech, which helps them pick up vocabulary and understand how to express their thoughts and feelings.

Listening skills are equally important, as they enable young children to absorb the sounds, intonation, and patterns of language spoken around them. By listening to others, they begin to understand the meanings associated with words and how to use them effectively in context.

While learning to read typically occurs later, the foundational skills necessary for reading—such as phonemic awareness and vocabulary recognition—are built during the early stages of language development. Exposure to spoken language and early literacy experiences, such as being read to, also foster an environment that facilitates language growth.

Thus, all these elements—social interaction, listening skills, and the beginnings of literacy through reading—are essential components in a child's overall language development during the critical early years.
