How did early humans living near oceans adapt to their environment?

a. they designed wood bridges and rope bridges
b. they use the tree trunks to create shelters
c. they learned how to fish and make boats
d. they hunted big game like bison and oxen

The answer is C. They learned how to fish and make boats.

The key to answering this question is to see what type of environment the people in question were living in. It states that they lived near oceans so the adaptation will be something related to living near a body of water.
