Solution:(b) Naming and holophrastic stage: In this stage, children use single words or holophrases, where one word conveys a complete idea, such as using "milk" to mean "I want milk."
(c) Telegraphic stage: Children begin combining two or three words in simplified phrases, omitting less important words, as in "want cookie" instead of "I want a cookie."
(d) Morphemic and transformational stage: At this stage, children start using morphological markers and begin applying basic transformational rules in language, leading to more grammatically structured sentences.
These three stages reflect the meaningful and progressive phases of early speech development in children.
