Concept:Learners have different abilities, needs, and learning styles, known as individual differences. Teaching must adapt to these differences rather than being uniform.Explanation:Every student is unique. Some learn faster, others need more time. A standardized approach ignores these differences and may not help all students. Individualized teaching means planning lessons based on each student's strengths and weaknesses. This helps every child learn effectively. For example, a student weak in reading may need extra support, while another strong in math can move ahead. The goal is to meet each learner where they are and guide them forward. Therefore, classroom teaching should be individualized, not standardized.Answer:Option B: individualized since there are individual differences among learners.
