Which risk increases when subsurface carbon sequestration targets exceed threshold?

💡 Explanation

Induced seismicity risk rises under high-volume carbon dioxide injection because pore pressure increases activate the mechanism of fault reactivation. Therefore, A is correct; earthquake risk rises, rather than the hydrate release, thaw, or tsunami scenarios driven via thermal or displacement mechanisms.
