Correct Answer:
B. Marine Plastic pollution
The correct answer is Marine Plastic pollution. The Great Pacific Garbage Patch is a large accumulation of marine plastic pollution in the North Pacific Ocean. It is a gyre of marine debris, mostly consisting of microplastics, located between Hawaii and California. The patch is formed by ocean currents that trap plastic waste. It is not air pollution (which affects the atmosphere), soil pollution (which affects the ground), or a mixture of all types of pollution. Therefore, Marine Plastic pollution is the correct answer.
