Detailed Answer Explanation

This question tests your understanding of sentence function and text organization. The relative clause 'which contradicted widely accepted theories' is nonessential. A comma closes this clause before the main verb 'challenged.' Each sentence in a well-constructed text serves a specific purpose. Consider what role this sentence plays in the argument: does it introduce, support, contrast, or conclude an idea? Understanding why an author includes specific sentences helps you grasp the overall argument. Each sentence should serve a clear purpose: introducing ideas, providing evidence, acknowledging counterarguments, or drawing conclusions. Identify the role to understand the structure.

Key Evidence:

• "The economist's analysis, which contradicted"

• "challenged policymakers"

Why others are wrong: B (A colon doesn't fit for closing a relative clause.), A (A semicolon is too strong for closing a relative clause.), D (Missing punctuation fails to close the nonessential relative clause.).
