问题如下：
Why was the US Department of Labor’s clarification of fiduciary duty in 2015 welcomed by the ESG investing industry?选项：
A.It allowed plans to invest in generating societal benefits in addition to financial return, as long as they were deemed appropriate for the plan’s investment objectives, return and risk
B.It provided a standard for economically targeted investments (ETIs)
C.It specified that, as long as the expected rate of return was commensurate with the rates of return offered by alternative investments with similar risk characteristics, ETIs were compatible with fiduciary duty
D.It incentivised pension funds subject to ERISA to invest in ETIs
解释：
A选项说在选择投资产品的时候，除了财务return也可以考虑投资一些会带来社会benefits的标的，只要他们能够匹配客户的投资目标，收益和风险特征。这个说法正确。
B选项说，US Department of Labor’s clarification of fiduciary duty提供了一个以赚钱为目标的投资标准，这个和ESG投资不相符。
C选项是说的是只要能满足预期收益和风险的匹配，ETIs就是满足受托责任的。这是克林顿时期的。
D选项是说，它鼓励更多Pension funds投资在以赚钱为目标的投资当中，这个并没有考虑到ESG，并不相符。
能否把这个题的背景和题意再详细解释一下。
