Concept:Mother tongue-based multilingualism uses the learner's home language as the foundation for schooling, then gradually introduces additional languages.
Explanation:Students begin their education in their mother tongue or home language.
This helps build strong cognitive and reasoning skills.
Later, they add at least two more languages in school.
This approach respects the child’s first language and makes learning new languages easier.
It also supports smooth transition from home to school language.
Multilingual children often show better academic performance and cognitive flexibility.
Answer:Option A: learners begin their schooling in mother tongue and move on to add many more (at least two) languages in school.
