At Alligator Reef (Florida Keys), coral colonies experiencing degradation-a problem facing reefs globally have been enhanced with transplanted fragments of elkhorn (a stony coral). This is a useful restoration approach but is challenging at scale since it involves cultivating and individually moving young stony coral pieces. In 2025, Samapti Kundu and her team announced a new approach: coating reef substrates with a simple-to-apply substance, made with inexpensive and abundant core components, which __________

Which choice most logically completes the text?

• A.

  offers a means of reef restoration that likely allows much broader implementation than the approach used at Alligator Reef does.

• B.

  is likely to require more costly components to ensure its stability when used for coral colonies as degraded as those at Alligator Reef.

• C.

  should be most beneficial for restoring reefs that predominantly consist of elkhorn coral colonies.

• D.

  should be able to simulate healthy reef signals even more closely when it is applied to degraded reefs than when it is applied to healthy reefs.
