Explanations:Prepositions are an essential part of the English language, used to indicate the relationship between a noun or pronoun and other parts of the sentence. In the context of the given sentence, the prepositions "on" and "in" are used to convey specific meanings related to policy and pronouncements.
The preposition "on" is often used to indicate the subject or topic of a policy. For example, "the policy on education" or "the policy on healthcare." In this case, "on" is used to specify the subject of the government's policy, which is Jammu and Kashmir. This usage is appropriate because it clearly indicates that the policy is focused on or related to Jammu and Kashmir.
The preposition "in" is used to indicate the source or location of pronouncements. For example, "pronouncements in the press" or "pronouncements in the media." In this context, "in" is used to indicate that the pronouncements are made within the context of the government's policy. This usage is appropriate because it suggests that the pronouncements are part of or related to the policy discussions or statements made by the government.
Other prepositions such as "for," "to," "about," and "from" do not fit the context as well. "For" is typically used to indicate purpose or benefit, "to" is used to indicate direction or recipient, "about" is used to indicate general topics, and "from" is used to indicate origin or source. None of these prepositions convey the specific relationship between the policy and the pronouncements as effectively as "on" and "in."
Therefore, the correct answer is "On, in," as it accurately reflects the relationship between the government's policy and the pronouncements made by the government.
