b. pangaea was destroyed by earthquakes
c. pangaea was damaged by erosion
d. pangaea split up, and the pieces moved apart to become the continents of today.

Explanation:

Alfred Wegener proposed the theory of continental drift, suggesting that the supercontinent Pangaea split into pieces that moved apart over time to form the present - day continents. Option a is incorrect as Pangaea didn't sink to the ocean floor. Option b is wrong because earthquakes didn't destroy Pangaea. Option c is also incorrect as erosion was not the cause of Pangaea's change. Option d aligns with Wegener's theory of continental drift.

Answer:

d. Pangaea split up, and the pieces moved apart to become the continents of today.
