Which outcome is accelerated as barrier islands destabilize?

💡 Explanation

Increased saltwater intrusion results from barrier island breakdown, because wave action exposes the land behind the islands, enabling greater marine inundation. This overwash process accelerates saltwater penetration, therefore saltwater intrusion increases, rather than the geological processes listed in the other options.
