Choose the sentence which has the appropriate use of Article/s:

Mathematics is an interesting subject.

The correct answer is Option (1) - Mathematics is an interesting subject.

• Option 1:
  "Mathematics is an interesting subject."

  • "Mathematics" is a subject name that is treated as a general discipline and is used without a definite article.
  • The phrase "an interesting subject" correctly uses the indefinite article "an" with a singular countable noun "subject."
  • This sentence follows standard article usage rules.

• Option 2:
  "The Tennis is not our national game."

  • Sport names like "tennis" are typically used without the definite article "the."
  • The correct form would be "Tennis is not our national game."

• Option 3:
  "I have had the lunch."

  • The definite article "the" before "lunch" implies a specific lunch known to both speaker and listener.
  • In general usage, we say "I have had lunch" unless referring to a particular lunch.

• Option 4:
  "Our examination is at the hand."

  • The idiom is "at hand" (meaning imminent or nearby), not "at the hand."
  • The use of "the" here is incorrect.
