Children in their early years scribble on the wall, floor and in notebooks. This stage in language learning is called

The correct option is emergent literacy.

Step-by-step Explanation:

1. Understanding Emergent Literacy: Emergent literacy is the term used to describe the early phase of language development that occurs before a child learns to read and write formally. It covers the developmental period from birth until the child reads and writes in conventional ways. During this stage, children develop foundational concepts about print, language, and communication.
2. Scribbling as a Milestone: When children scribble on walls, floors, and notebooks, they are engaging in their first attempts at writing. To a child, these marks are meaningful representations of thoughts and communication. This behavior shows their growing understanding that written marks represent language, which is a critical stepping stone to formal literacy.
3. Distinguishing from Other Options:
- Writing skills refer to the conventional ability to form letters, spell, and compose text, which comes with formal education.
- Graphic development is a term related to the physical progress in drawing and motor skills, rather than the specific language learning framework.
- Scribbling is the action itself, but the overall language-learning developmental stage is scientifically termed emergent literacy.
