Correct option is A
emergent literacy development
When a teacher of class one encourages her learners to scribble, draw, and write whatever they want on the walls, she is fostering emergent literacy development. Emergent literacy refers to the early stages of literacy development, where children begin to understand and use symbols and print. This activity allows children to experiment with writing and drawing, which are key components of literacy, in a free and creative environment. It helps them develop an understanding and appreciation for written language, even before they formally learn to read and write.
