Which of the following is NOT a common type of loan mentioned in corruption cases?

In the context of corruption cases, the focus tends to be on transactions that are designed to conceal wrongdoing or facilitate corrupt practices. A legitimate loan made at market rates wouldn't typically fit this narrative because it adheres to standard lending practices and does not involve deception or illicit intent.

Corruption often involves loans that are not genuinely intended to be repaid or that are misrepresented, making them tools for bribery or other forms of unethical behavior. For instance, outright payments that are falsely described as loans can be used to disguise bribes. Similarly, loans made on favorable terms or where a third party handles the payments can serve to obscure the true nature of the financial transaction. These types of arrangements may provide cover for illegal payments or benefits exchanged between parties involved in corrupt activities.

Thus, the reason B stands out as not commonly found in corruption cases is that it represents a straightforward, lawful transaction, whereas the other types involve elements of deceit or arrangements that are characteristic of corrupt practices.
