Final answer:
The correct option is 4) Colorful pictures.
Books for babies facilitate oral language development, stimulate imagination through colorful pictures, and can be relatable and enjoyable for all age groups. They support cognitive and psychosocial growth by using repetitive, simple text and wordless storytelling.
Step-by-step explanation:
Books for babies are known to be significant in the promotion of oral language development. They provide the foundation by introducing simple songs, rhymes, and the rhythm of spoken language, which are crucial at an early age when children are rapidly learning new words and starting to understand the structure of sentences. The early exposure to language and reading aids in cognitive development, including the ability to sing along, ask questions and anticipate routines. The repetitive and melodic nature of the content in baby books makes it easier for infants and toddlers to grasp language.
Moreover, these books are beneficial in enhancing children's social and psychological development, helping them establish close relationships, and improving their ability to cooperate and participate in group activities. Brightly colored pictures and thematic content that is relatable to children can make these books enjoyable for all age groups and support the learning process by maintaining engagement. Books with minimal or no text, often referred to as wordless books, stimulate imagination and storytelling skills as children invent narratives based on the visual cues.
