D. The listeners were i. creatures of the Traveller's imagination.
ii. shadows created by the moonlight.​

i. Creatures of the Traveler's imagination.

Explanation:

Walter De La Mare's poem The Listeners is about a traveler knocking on a door of a lonely house in the woods. Though without any response from the 'occupants' of the house, the traveler proceeded to speak as if there is someone listening to him.

The poem shows the traveler asking "Is there anybody there?", and getting no answer. He went on to say "‘Tell them I came, and no one answered, That I kept my word," and then went on his way. Though there is no direct reference to who the listeners are inside the house, we can assume that they are 'ghosts' or phantoms. They can also be creatures that the traveler imagined to live in the deserted house.

Thus, the correct answer is option i.

since it is asking for her reaction to elnora's trouble at school you can rule out any answers with a positive response (b). then you can rule out (d), this is because it does not show the mother's reaction but the daughter's response. that leaves you with two options (a) and (c), by looking at the options you can rule out (c) because it isn't referring back to elnora's issues at school.
