Answer: B, planting mangrove forests
Explanation:
Healthy mangrove forests provide homes for roosting bird species, protect coastal communities from storm surges, and provide a nursery habitat for juvenile coral reef organisms.
A is incorrect because the construction of a seawall would prevent the threat of storm surge but would not provide a habitat for roosting bird species nor help the health of the coral reef.
C is incorrect because the construction of an offshore breakwater would prevent the threat of storm surge but would not provide a habitat for roosting bird species. Its construction would also likely damage the nearby coral reef.
D is incorrect because creating large sand dunes could initially protect from storm surges, but this can also cause erosion. Sand dunes would not provide habitat for roosting bird species nor would they help to protect the health of the coral reef.
