Question 39. Which of the following best paraphrases the underlined sentence in paragraph 2?

Exemptions for research are tightly drawn and explicitly preclude commercial elements, acting as a bulwark against carbon-credit schemes masquerading as science.

A. Research projects may sell credits if peer-reviewed results confirm permanent carbon storage capacity and demonstrate additionality across baseline scenarios.

B. The research exception is narrow and bans commercial motives, blocking offset-market projects disguised as experiments from circumventing restrictive treaty obligations.

C. Commercial pilots are permitted when accompanied by transparent registries and post-trial remediation funds ensuring accountability and environmental harm prevention.

D. Any study linked to patents is invalid unless sponsored by intergovernmental agencies guaranteeing scientific integrity and prohibiting private profit extraction.
