问题如下：
To have lower credit risk, it would be preferable to engage in a trade where there is a lower probability of a default by the counterparty when the contract is in-the-money. This will happen if the counterparty enters a transaction to hedge an operating exposure. Buying gas from ___ is a good example.
选项：
A. A trading firm
B. A gas producer
C. A distributor
D. Either A, B, or C
解释：
B is correct.
考点：Right-Way Risk
解析：
A gas producer has a natural operating exposure to gas. If the producer sells gas at a fixed price, the swap will lose money if the market price of gas goes up. In this situation, however, there is little risk of default because the producer is silting on an inventory of gas. A trading firm or distributor could go bankrupt if the transaction loses money.
