The Supreme Court is the head of what's called the JUDICIAL branch. This branch of government INTERPRETS the laws, to make sure they are constitutional (or follow the Constitution). (In contrast, the legislative branch, like Congress, makes and passes laws; and the executive branch, headed by the President, enforces laws, or makes sure they're followed.)
Does the Supreme Court interpret the meaning of laws? YES: that's what we just determined above. Judicial review is determining if a law is constitutional. Do they do this? Again, YES, if you look at the definition above. Now, can it overrule its previous decisions? YES, it does it all the time! The only thing it CAN'T do is PASS laws: that's what the legislative branch is for, NOT the judicial branch.
Answer: B
