Detailed Answer Explanation

This question tests your understanding of sentence function and text organization. 'The mechanism by which the virus evades the host's immune system' is the complete subject. No punctuation is needed before the main verb 'has.' 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 mechanism by which the virus evades"

• "has implications for vaccine development"

Why others are wrong: A (A colon incorrectly separates the subject from its verb.), C (A comma incorrectly separates the subject from its verb.), D (A semicolon incorrectly separates the subject from its verb.).
