未来你听见了吗

Because the budget package in Congress promises a combination of higher taxes and reduced spending that may slow economic growth, many in the credit markets wonder whether the Federal Reserve will compensate and help the economy by keeping interest rates low, or perhaps even if they push them lower.
A. by keeping interest rates low, or perhaps even if they push
B. by its keeping interest rates low, or perhaps even by their pushing
C. by keeping interest rates low, or perhaps even by pushing
D. through their keeping interest rates low, or perhaps even push
E. through their keeping interest rates low, or perhaps it will even push

答案为C，解析中说道剩下选项的their/they为指代错误，我没看出来哪里指代有问题阿...麻烦nn指教一下~~

LZ你觉得they/ their指代的是？

额额更正一下问题，their的确指代有问题，我觉得their应该是its，指代经济体的interest rate。但是its keeping看不懂这个结构，解析又说没错只是不简洁...此外解析说they是无指代，their是指代错误，而我觉得their也是无指代，Prep中多次出现这两个表述，是不是这两种表述是一个意思呢？ LZ是新手望NN不胜赐教~~
