a by generating tsunamis, leading to flooding, soil erosion, and infrastructure destruction
b by altering the course of rivers and the disrupting aquatic habitats
c by increasing atmospheric pollution and air - quality degradation
d by displacing soil, rocks and debris to reshape the terrain

Explanation:

Underwater earthquakes can displace a large volume of water, generating tsunamis. Tsunamis can cause flooding, soil erosion, and destruction of infrastructure in coastal areas. Options B, C, and D are not the primary impacts of underwater earthquakes on coastal areas.
