Select the most appropriate option that will fill in the blank number 5.
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. an.
- 'A' is used before words that start with consonant sounds (“a sample” or “a model”), even if the consonant sound is made by a vowel (“a unit”). Conversely, 'an' is used before words that start with vowel sounds (“an equation” or “an element”), even if the word starts with a silent consonant (“an hour”).
- The noun "endless" starts with the vowel sound hence, "an" will be the suitable article here.
Hence, the chosen option will be correct.
