Answer;
D. omega-3 fatty acids
Explanation;
-Fatty acids consist of chains of carbon atoms linked together by chemical bonds. On one end (terminal) of the carbon chain is a methyl group (a cluster of carbon and hydrogen atoms). On the other terminal is a carboxyl group (a cluster of carbon, oxygen and hydrogen atoms).
-Omega-3 fatty acids are a class of essential polyunsaturated fatty acids with the double bond in the third carbon position from the methyl terminal.
-Omega 3 fatty acids or Eicosanoids are important as they lower blood pressure, prevent blood clot, protect against the irregular heart beat and reduce inflammation.
