In the question below four words are given in bold. These four words are may not be in their correct position. The sentence is then followed by options with the correct combination of words that should replace each other in order to make the sentence grammatically and contextually correct. Find the correct combination of the words that replace each other.

To determine if any of the bolded words need to be replaced, let us analyze the context and grammatical correctness of the sentence:

The sentence is: "The Commission for Air Quality Management in NCR and the adjoining areas (1) areas (2) has developed a framework for the effective (3) prevention and control of stubble burning (4)."

Let us look at the placement of the bolded words:
1. "adjoining" correctly describes "areas" (the regions bordering the National Capital Region).
2. "areas" is the noun referring to those regions, which fits perfectly after "adjoining".
3. "prevention" acts as a noun describing the act of stopping something before it happens, which forms a parallel structure with "control" ("prevention and control of...").
4. "burning" is the gerund noun in "stubble burning", which is the correct and widely used term for the practice of clearing agricultural residue by setting it on fire.

Since all the words are grammatically correct and contextually logical in their current positions, no words need to be exchanged.

Therefore, the correct answer is No correction required.
