Which of the following definitions best describes '(7Z,10Z,13Z,16Z)-19,20-epoxydocosatetraenoate'?

A. An icosanoid anion that is the conjugate base of 14,15-EET, obtained by deprotonation of the carboxy group; major species at pH 7.3.
B. A docosanoid anion that is the conjugate base of (7Z,10Z,13Z,15E,19Z)-17-oxodocosapentaenoic acid, obtained by deprotonation of the carboxy group; major species at pH 7.3.
C. An icosanoid anion arising from deprotonation of the carboxylic acid function of any hydroperoxyicosatrienoic acid.
D. A docosanoid anion that is the conjugate base of (7Z,10Z,13Z,16Z)-19,20-epoxydocosatetraenoic acid, obtained by deprotonation of the carboxy group; major species at pH 7.3

Answer: A docosanoid anion that is the conjugate base of (7Z,10Z,13Z,16Z)-19,20-epoxydocosatetraenoic acid, obtained by deprotonation of the carboxy group; major species at pH 7.3
