Choose the sentence where the word 'Right' has been used appropriately as an adverb.

Serves him right! He stood right in my way

The correct answer is Option (4) - Serves him right! He stood right in my way

Explanation:

The word “right” can function as different parts of speech depending on usage — adjective, noun, or adverb.
Here, we’re looking for its use as an adverb.

Option Analysis:

1. He is the right man for the job. → Incorrect
   Here, “right” describes the noun “man,” so it’s an adjective, not an adverb.

2. I demand my right to free speech. → Incorrect
   Here, “right” is used as a noun (a claim or entitlement).

3. That is a fault which will right itself. → Incorrect
   Here, “right” is a verb, meaning “to correct.”

4. Serves him right! He stood right in my way. → Correct
   In both instances, “right” functions as an adverb:

   • Serves him right! → modifies the verb phrase “serves him,” meaning “justly” or “deservedly.”

   • He stood right in my way → modifies the preposition “in,” meaning “exactly” or “directly.”

 Therefore, Option 4 correctly uses “right” as an adverb.
