Identify the grammatically correct form of the given sentence.
Sentence: She is not the only girl who plays a football in the community park.
I. She is not the only girl who plays football in the community park.
II. She is not a only girl who plays football in the community park.

Correct option is B

The grammatically correct sentence is (b) Only I is correct.
· In I, the sentence correctly omits the article "a" before "football" because "football" is an uncountable noun when referred to as a sport.
· In II, the phrase "a only girl" is grammatically incorrect because the article "a" cannot directly precede "only"; it should be "the only girl."
Grammatical Rule Used:
· Use "the" with "only" because "only" is a definitive adjective, requiring a definite article.
· Uncountable nouns like sports names (football, cricket) do not require articles unless specified for a particular object.
Example:
· Correct: She is the only student who passed the exam.
· Incorrect: She is a only student who passed the exam.
 Information Booster:
· "Only" always takes "the" article, never "a" or "an."
· Sports names are treated as general activities and do not require "a" or "an."
