Which of the following definitions best describes '(13Z,16Z,19Z,22Z,25Z)-octacosapentaenoic acid'?

A. A very long-chain omega-3 fatty acid that is hexacosanoic acid having six double bonds located at positions 8, 11, 14, 17, 20, 23 (the 8Z,11Z,14Z,17Z,20Z,23Z-isomer).
B. A very long-chain omega-3 fatty acid that is hexatriacontanoic acid having six double bonds located at positions 18, 21, 24, 27, 30 and 33 (the 18Z,21Z,24Z,27Z,30Z,33Z-isomer).
C. A very long-chain omega-3 fatty acid that is octacosanoic acid having five double bonds located at positions 13, 16, 19, 22 and 25 (the 13Z,16Z,19Z,22Z,25Z-isomer).
D. A docosahexaenoic acid having six cis-double bonds at positions 4, 7, 10, 13, 16 and 19.

Answer: A very long-chain omega-3 fatty acid that is octacosanoic acid having five double bonds located at positions 13, 16, 19, 22 and 25 (the 13Z,16Z,19Z,22Z,25Z-isomer).
