解释：

C is correct. One of the most common criticisms of ESG investing is the difficulty for investors to correctly identify and appropriately weigh ESG factors in investment selection. Critics express concerns about the precision, validity, and reliability of ESG investment strategies. One concern is that ESG mutual funds and exchange-traded funds might be holding investments in companies acknowledged as “bad actors” in one or more of the ESG dimensions.
