Final answer:
Roosevelt's statement indicates that protecting human rights inherently supports the protection of property rights since the right to own property is seen as part of inalienable human rights.
Step-by-step explanation:
The statement that Roosevelt means by "human rights and property rights are fundamentally and in the long run identical" suggests that the protection of human rights inherently includes the protection of property rights. Human rights are considered fundamental and inalienable, which include the right to own property as well as liberties such as freedom of speech and religion.
By ensuring human rights, a government by extension protects property rights because ownership is seen as an expression of one's liberty and autonomy. Hence, the correct answer is b) Protecting property rights supports human rights.
