The correct answer is C.

In the period leading up to the 2007/2008 financial crisis, there was a significant misalignment of incentives across the financial industry. Mortgage originators largely operated on an "originate-to-distribute" model, meaning they made loans with the intent to sell them immediately to investment banks for securitization rather than keeping them on their balance sheets. This structure prioritized loan volume over loan quality, as the originators bore little to no long-term risk for defaults. Furthermore, credit rating agencies were compensated by the very institutions issuing the securities. This created a clear conflict of interest, where rating agencies were incentivized to provide overly optimistic ratings (e.g., AAA ratings for subprime-backed securities) to retain and attract business from the issuers.

A is incorrect. Mortgage originators often prioritized high-risk, subprime loans because they generated higher yields and could be easily sold off. Investment banks were interested in packaging these loans into asset-backed securities to sell at a premium, not necessarily focusing on low-risk underlying assets.

B is incorrect. Credit rating agencies frequently provided overly optimistic and inaccurate ratings, failing to reflect the true underlying risk of the asset-backed securities.

D is incorrect. A major contributing factor to the crisis was that investors heavily relied on the flawed ratings provided by credit rating agencies, rather than conducting their own comprehensive due diligence and risk analysis.
