Select whichever preposition or determiner you consider the most appropriate for the blank space.
______________ travel industry is changing rapidly.

Correct option is C

The word that can be filled in the blank is ‘the’ to make the sentence grammatically and contextually correct.
· ‘The’ is a definite article used to specify a particular noun, in this case, "travel industry." It indicates that the speaker is referring to the specific travel industry that is changing rapidly.
· Grammatical rule involved: The definite article 'the' is used before singular and plural nouns when the noun is specific or known to the reader.
· As per the context, the word ‘the’ fits in very well, and hence, it is the correct option.
Meanings of other given words:
· An - an indefinite article used before words starting with a vowel sound; it does not specify a particular noun.
· A - an indefinite article used before words starting with a consonant sound; it also does not specify which travel industry.
· No article - would imply that no specific travel industry is being referred to, which does not align with the context.
· Thus, all the other given words have different meanings and do not fit in the context of the sentence.
