Answer: D

The language expressions used in fund promotion materials should be accurate and clear, and special attention should be paid to: ① Without sufficient evidence, expressions such as "stable performance", "excellent performance", "among the top", "the first", "the biggest", "the best" and "the only" should not be used; ② Do not use expressions such as "sit and enjoy wealth growth", "enjoy growth with peace of mind" and "enjoy bull market", which make fund investors ignore risks; (3) Do not use expressions that unilaterally emphasize the time limit of centralized marketing, such as "want to buy as soon as possible" and "purchase opportunity"; ④ Do not use expressions that mislead fund investors, such as "the net value is normalized".
