The power that allows Congress to take private property for uses such as an interstate highway system or a national park is known as the power of eminent domain. To arrive at this answer, let's break down the options provided:

a. The commerce power: This refers to Congress's authority to regulate interstate and international trade, but it does not grant the power to seize private property for public use.

b. The power of eminent domain: This power allows the government to take private property for public use, as long as just compensation is provided to the property owner. This option aligns with the description provided in the question.

c. The borrowing power: This refers to Congress's authority to borrow money on behalf of the United States government. It does not grant the power to seize private property.

d. The power to tax: This power allows Congress to impose taxes on individuals and businesses to generate revenue for the government. Although taxes may be used to fund projects like highways or national parks, this power does not grant the authority to take private property.

Therefore, the correct answer is b. the power of eminent domain.
