An English teacher taught 'interjection' by using Concept Attainment Model. In this context, which one of the following activity is not required?

Correct option is A

Answer: (a) Selected positive and negative exemplars on 'interjection' after presenting it to students.
Explanation:
In the Concept Attainment Model, exemplars are presented before the concept is named. Students compare positive and negative examples, generate hypotheses, describe their thinking, and then produce their own examples. Selecting exemplars after presenting the concept violates the model's sequence, making it the activity that is not required.
