Solution:
The correct answer is C) ‘The, A’. In English grammar, the adjectives ‘a’, or ‘an’ and ‘the’ are usually called Articles. The articles, ‘a’ or ‘an’ are used for an indefinite person or thing spoken of; as a doctor; that is, any doctor. Hence they are known as indefinite articles. The article ‘the’ is used to point at a particular person or thing, hence being known as a definite article. From the given statement ‘____ Ganga is ___ sacred river’, it is evident that the first article would be ‘the’ because ‘Ganga’ is a proper name. The second article has to be an indefinite article, making article ‘a’ the correct choice as the word sacred doesn't have a vowel sound. Therefore, the required option is C).
