- Both A and R are true and R is the correct explanation of A.
- Both A and R are true and R is not the correct explanation of A.
- A is true but R is false.
- A is false but R is true.
Answer
Both A and R are true and R is not the correct explanation of A.
Explanation — The Oyashio is indeed a cold ocean current that flows along the eastern coast of Russia and Japan. It brings nutrient-rich cold water, which supports the growth of plankton and results in highly productive fishing grounds. However, the richness of the fishery is a result of the nutrients and mixing of currents, not simply because the Oyashio is cold. Therefore, while both statements are true, the reason does not directly explain the assertion.
