Answer: d) fatty acids in both triacylglycerols and in phosphoacylglycerols vary.

Explanation:

Triglyceride is defined as an ester derived from three (tri - and glyceride) fatty acids and glycerol. Triglycerides, as well as vegetable oil, are the primary components of body fat in humans and other vertebrates.

Phosphoacylglycerols are glycerol triesters in which one group of - OH is esterified with phosphoric acidand and two groups of - OH are esterified with fatty acids, which is then esterified into an alcohol. Phosphoacylglycerols have a configuration of "head and two tails," and are major components of cell membranes.

Hence, the correct statement is d) fatty acids in both triacylglycerols and in phosphoacylglycerols vary.
