Detailed Answer Explanation

This question tests your understanding of sentence function and text organization. 'Protracted and frequently contentious though they were' is a concessive clause (inverted 'though they were protracted'). A comma closes this clause before 'ultimately produced.' 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 treaty negotiations, protracted and frequently contentious though they"

• "ultimately produced an agreement"

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