Answer 1

Answer: The correct answer is A. Coastal regions are highly impacted by human activity.

Step-by-step explanation:

Human activity near coastal regions includes the use of inlets, beach bed changes, dredging of waterways, commercial shipping, recreational boating, land development, hotels, houses, and industrial plants. All of this activity is highly disruptive, risky, and impactful to the inhabitants of the local ecosystems.

Answer 2

A. Coastal regions are highly impacted by human activity

Step-by-step explanation:

Since I'm not completely sure I will debunk the others and let you decide.

-Option D- says they are ONLY concerned with the coast. KEY WORD only. Oceanographers study the ocean and not just the coast.

-Option C- also not true, the coast is probably the easiest portion to access but growing technologies and inventions like submarines made the ocean easier to study.

-Option B- I'm not sure of this one. I would think previous studies would start with the coast because it's the easiest to access

-Option A- Man-made beaches, water pollution, shoreline erosion. changing an organisms environment disrupts the ecosystem and human activities cause a significant decline in coastal habitats. i think this is the answer
