Select the correct answer using the code given below:

• A. 1 only
• B. 2 only
• C. Both 1 and 2
• D. Neither 1 nor 2

Answer 1

The correct option is B 2 only

Explanation:

• Statement 1 is incorrect: No lagoon between the fringing reef and shore. Fringing reefs are reefs that grow directly from the shore. While there may be areas of shallow intertidal or sub-tidal sand bottom lying between the beach and the inshore edge of coral growth, there is no lagoon between the reef and shore
• Statement 2 is correct: An atoll is a roughly circular (annular) oceanic reef system surrounding a large (and often deep) central lagoon.
