In the following sentence, the bracketed part is grammatically incorrect. Choose the option that best improves the sentence: The Centre should revisit (their) draft and incorporate the inputs of the report submitted by the standing committee and an expert panel.

Introduction / Context:
This sentence improvement question checks pronoun agreement, especially with collective or institutional nouns. The sentence refers to "The Centre", which in Indian English commonly means the central government. You have to choose a pronoun that correctly refers back to this singular institutional noun in formal writing.

Given Data / Assumptions:

• Original sentence: The Centre should revisit "their" draft and incorporate the inputs of the report submitted by the standing committee and an expert panel.
• "The Centre" is a singular noun referring to the central government.
• The word "draft" is clearly singular.
• The register is formal and likely from a newspaper editorial or exam passage.

Concept / Approach:
In standard formal English, singular institutions such as the government, the court, or the company are typically referred to by the pronoun "its". The pronoun "their" is plural, and although sometimes used with collective nouns in informal British English, exams generally expect strict grammatical agreement. The form "it’s" is a contraction of "it is" or "it has" and is not used as a possessive. Therefore, the correct choice here is the possessive pronoun "its", which matches the singular "Centre" and shows possession of the draft.

Step-by-Step Solution:
Step 1: Identify the antecedent of the pronoun: "The Centre".Step 2: Decide whether this antecedent is treated as singular or plural in formal written English. In exam contexts, it is treated as singular.Step 3: Choose the correct singular possessive pronoun: "its".Step 4: Insert "its" into the sentence: "The Centre should revisit its draft and incorporate the inputs of the report submitted by the standing committee and an expert panel."Step 5: Read the whole sentence to verify that pronoun agreement and meaning are both correct.

Verification / Alternative check:
If you try option B, "it’s", the sentence becomes "The Centre should revisit it is draft", which clearly does not make sense. Option C, "these", does not function as a possessive pronoun and cannot directly modify "draft" in this context. Option D, "No improvement", would keep the plural "their" even though the subject is singular. When you compare all possibilities, only "its" gives a grammatically correct and natural reading.

Why Other Options Are Wrong:

• Option B: "it’s" is a contraction of "it is" or "it has", not a possessive form, so it cannot correctly refer to the draft belonging to the Centre.
• Option C: "these" normally points to plural nouns and is a demonstrative determiner, not a possessive pronoun; it does not make sense before "draft".
• Option D: "No improvement" fails because "their" is a plural pronoun, which does not strictly agree with the singular "Centre" in formal exam English.

Common Pitfalls:
A major pitfall is confusing "its" and "it’s". The form without an apostrophe is the possessive, while the form with an apostrophe is a contraction. Many students also overuse "their" after collective nouns, influenced by everyday speech or social media usage. In competitive exams, however, you should default to strict number agreement and standard formal conventions. Always check whether the noun is grammatically singular and whether the pronoun form matches that number and function.

Final Answer:
The correct improvement of the bracketed pronoun is its.
