Choose the correctly spelled word to replace the highlighted word in the sentence. If the highlighted word is already spelled correctly, select ‘No replacement required’.

Ravi introduced his new colleague as an acquaintence from his university days.

The correct answer is acquaintance.

Explanation:
The word highlighted in the given sentence is "acquaintence", which contains a spelling error. The suffix used at the end of this word should be -ance rather than -ence.
Therefore, the correct spelling of the word is acquaintance.

Definition & Usage:
An acquaintance is a person one knows slightly, but who is not a close friend. It is formed from the base verb acquaint plus the noun suffix -ance.

Option Breakdown:
• acquaintance: Correct spelling.
• acquantance: Incorrect (missing the letter 'i' after 'a').
• acquaintence: Incorrect (uses '-ence' instead of '-ance').
• No replacement required: Incorrect because "acquaintence" in the sentence is misspelled and requires correction.
