The correct answer is D. Claim of policy
Explanation:
Claims of policy differ from value and fact claims because they state what entities, organization or societies should or should not do. This means, claims of policy are related to actions, and due to this, they commonly suggest a specific policy or plan should be followed.
In the case of the claim presented, this can be classified as a claim of policy because it addresses a course of action school districts should follow "school districts should pay more attention to the learning habits of students and their ability to synthesize and apply knowledge" which means it states what school as an entity should do and what should not do "Instead of focusing solely on standardized testing".
