Detailed Answer Explanation

This question tests your understanding of sentence function and text organization. The participial phrase 'identified through functional MRI studies' is parenthetical. A comma closes this phrase before the main verb 'becomes.' 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 neural pathway...identified through functional MRI"

• "becomes hyperactive in patients"

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