B

Test question analysis: This question mainly tests students’ accurate understanding of Locke’s ideas. The elimination method can be used to answer this question. The material is intended to explain that the law is to protect and expand people's freedom, but does not reflect the relationship between law and freedom. The material does not reflect "limiting the power of the government", so the statements A and D do not meet the meaning of the question. From the ancient and modern legal systems, we can see that law is a tool to maintain rule and is not specifically established to protect human rights, so item C is also wrong. So choose B.
