Answer 1

Hint: Prepositions are the function words that combine a noun phrase or used to show a relationship between words in a sentence. For example, she was sitting on the chair. Here, on is a preposition that is being used to connect the verb, ‘sitting’ with the noun phrase, ‘the chair’.

Complete answer:
From the hint given to us, we understand what prepositions are. From the given context of the sentence, we infer that the suitable preposition must indicate a place or a position. Preposition of place comprises of the following function words:
In - It is used to indicate a closed space or a region. For example, she lives in a mansion. We observe that it does not fit the context of the given sentence and hence, we can say that it is not the suitable preposition.
At - It is used to indicate a location or a position. For example, they were staying at a friend’s place. We observe that it does not fit the context of the given sentence and hence, we can say that it is not the suitable preposition.
Under - It is used to indicate something at a lower position, For example, the cat was sleeping under a tree. We observe that it does not fit the context of the given sentence and hence, we can say that it is not the suitable preposition.
Over - It is used to indicate to be at the top of something. For example, we were flying over the Swiss Alps. We observe that it does not fit the context of the given sentence and hence, we can say that it is not the suitable preposition.
On - It is used to indicate the touching of the surface from the top. For example, the book is lying on the table. We observe that it correctly fits the context of the given sentence and thus, it is the correct answer.

Note: It is to be noted that while solving such questions one must be familiar with prepositions. It is also to be noted that the meaning of the prepositions can be interpreted from the contexts they are used.
