D. It has little to do with the operation of the fund manager (correct answer)

Correct answer: D. The general direction of the "enhanced index fund" can follow the index, but its ultimate goal is to obtain the income higher than the index increase, so the fund manager often takes out some money to buy other stocks that do not belong to the index basket. Therefore, the operation level of fund managers is required to be higher, which will directly affect the final income.
