Which statement best describes the main cause of the 2008 housing market crash in the United States?

The crash was driven largely by risky mortgage lending and a sharp decline in home values, which left many borrowers unable to keep up with their mortgage payments. As the economy weakened and unemployment rose, more homeowners fell behind or defaulted, leading to foreclosures and further declines in the housing market. Choice A best describes this problem; high interest rates alone were not the main cause.
