Select the most appropriate option to substitute the underlined segment in the following sentence. Choose ‘No improvement’ as an answer if the sentence is grammatically correct. I can hear the band which is playing patriotic tunes, in the playground.

Correct answer: No substitution

Explanation: The correct answer is A.✅ The phrase "playing patriotic tunes" is grammatically and contextually correct. ✅"Patriotic tunes" (songs that express patriotism) is a proper noun phrase. The clause “which is playing patriotic tunes” correctly describes the band using a present continuous tense. ❌"Patriot tunes" – “Patriot” is a noun, not an adjective. ❌"Patriotic tuning" – “Tuning” refers to adjusting instruments, not performing music. ❌"Patriotically tuned" – awkward and incorrect usage in this context. Correct as is: I can hear the band which is playing patriotic tunes, in the playground.
