Which Path Could a Carbon Atom Follow If It Began $\rightarrow$

Which path could a carbon atom follow if it began in an amino acid in a protein in some tuna that was eaten by a cat and eventually ended up in a lipid in the cell membrane of one of the cat's muscle cells?

A) Amino acid $\rightarrow$ citric acid cycle $\rightarrow$ acetyl CoA $\rightarrow$ fatty acid $\rightarrow$ triglyceride $\rightarrow$ cell membrane
B) Amino acid $\rightarrow$ acetyl CoA $\rightarrow$ citric acid cycle $\rightarrow$ pyruvate oxidation $\rightarrow$ cell membrane
C) Amino acid $\rightarrow$ pyruvate oxidation $\rightarrow$ gluconeogenesis $\rightarrow$ glucose $\rightarrow$ glycerol $\rightarrow$ triglyceride $\rightarrow$ cell membrane
D) Amino acid $\rightarrow$ electron transport $\rightarrow$ citric acid cycle $\rightarrow$ acetyl CoA $\rightarrow$ lipid $\rightarrow$ cell membrane
E) Amino acid $\rightarrow$ citric acid cycle $\rightarrow$ acetyl CoA $\rightarrow$ pyruvate $\rightarrow$ glycolysis $\rightarrow$ glycerol $\rightarrow$ triglyceride $\rightarrow$ cell membrane
