Words B and C and words D and E are to be interchanged as mentioned. In the place of word B, an auxiliary verb is required to support the verb 'crowded' and in the place of word C, a preposition is required to describe their position. Accordingly, word B 'around' is a preposition and word C 'were' is an auxiliary verb that can take each other's place. Similarly, in the place of word D, a verb is required and in the place of word E, a noun is required. Accordingly, word D 'Nilgiris' is a noun and word E 'waiting' is a verb and thus they interchange their positions, respectively.
The correct sentence is: Families with children were crowded around the boxy windows, waiting for the promised views of the Nilgiris.
Hence, the correct answer is option (b).
Note:
Auxiliary verb: A verb that gives grammatical information that is not given by the main verb of a sentence. It supports the main verb. Auxiliary verbs help to form the various tenses, moods, and voices of other verbs. The principal ones are be, do, and have. Example: She will sing a song tomorrow. Here, 'will' is the auxiliary verb that supports the main verb 'sing'.
A Preposition is a word placed before a noun or a pronoun or a noun equivalent (pronoun, adverb, gerund, infinitive, adverbial clause, or any clause that can be used as the object of the preposition) and shows a relationship in space or time or a logical relationship between two or more people, places, or things in a sentence.
Examples
I. The teacher scolded the child for being late.
II. We're going to a party.
· The words in bold are called prepositions because they normally take position before (pre) a noun/pronoun or a noun equivalent (pronoun, adverb, gerund, infinitive, adverbial clause, or any clause that can be used as the object of the preposition.
· The noun/pronoun which is used with a preposition is called its Object.
