Concept:Language skills (listening, speaking, reading, writing) are most effectively developed when taught together, not in isolation.
Explanation:Real communication uses multiple skills simultaneously.
For example, speaking involves listening; writing involves reading.
Teaching skills separately creates artificial practice.
Integrated learning helps internalise grammar and usage naturally.
Challenging drills or focusing on one skill at a time limit real-world application.
Written tests alone ignore oral skills.
Therefore, the best approach is to integrate all language skills in lessons.
Answer:C. if they are dealt with in an integrated manner.
