Which long-term outcome occurs when rising sea levels breach coastal barrier islands?

A)Increased tidal prism of backbays✓

B)Stabilization of freshwater coastal aquifers

C)Decreased sediment supply offshore

D)Expansion of coastal mangrove forests

💡 Explanation

Increased island breaching causes a larger tidal prism because tidal currents redistribute sediment through the breach, therefore the bays' volume increases to accommodate storm surges better, rather than leading to aquifer stabilization if saltwater intrusion intensifies.
