Explanation:
The communicative approach to ELT (English Language Teaching) emphasizes the importance of communication in language learning. It focuses on developing learners' ability to use language in authentic and meaningful contexts.

Shift from form-based to a meaning-based approach:
The correct answer is option 'A', which states that the development of language learning or teaching involves a shift from a form-based to a meaning-based approach. This means that the focus moves away from simply learning grammatical rules and structures towards understanding and using language for real-life communication.

In a form-based approach, the emphasis is on learning grammar rules, vocabulary, and sentence structures in a systematic manner. Learners are often required to memorize and repeat sentences and phrases without necessarily understanding their meaning or how they are used in real-life situations. This approach tends to prioritize accuracy over fluency.

On the other hand, the meaning-based approach focuses on developing learners' ability to understand and use language in authentic contexts. It encourages learners to communicate meaningfully, even if they make mistakes or use language creatively. In this approach, the emphasis is on the practical use of language for communication rather than on the correctness of grammatical structures.

Benefits of a meaning-based approach:
- Learners are more motivated and engaged as they are able to use language in meaningful ways.
- Learners develop their communicative competence, which involves not only grammatical accuracy but also the ability to use language appropriately in different social and cultural contexts.
- Learners become more confident in using English for real-life communication.
- Learners develop their listening, speaking, reading, and writing skills in an integrated and holistic manner.
- Learners are exposed to authentic and varied language input, which helps them develop their understanding of different accents, dialects, and registers of English.

Conclusion:
The shift from a form-based to a meaning-based approach in ELT is a fundamental aspect of the communicative approach. It allows learners to develop their language skills in a more authentic and meaningful way, enabling them to use English effectively for communication purposes.
