Which of the following statements about enol content are correct?

The order is pentane-2,4-dione (about 80%) > ethyl acetoacetate (about 8%) > propanone ($\sim 10^{-6}\%$). Diethyl malonate has two ester groups, whose carbonyls are poor partners for enolisation, so its enol content is far below that of ethyl acetoacetate. Statements (C) and (D) are wrong.
