Explanation: Please note that the (2) marking in the question has been incorrectly placed. We will just find the third para beginning ourselves and work with that. We can see that both C and D can be used to introduce the third para and would make it better. A is eliminated. B is not the point of this para and E is completely unrelated. Between C and D, C is more consistent with the tone of the passage and a more interesting way to begin.
