Option b is incorrect ( Sphingomyelin is a phospholipid with a glycerol phosphate backbone. )
Explanation: Sphingomyelin consists of a phosphocholine head group, a sphingosine, and a fatty acid. It is one of the few membrane phospholipids not synthesized from glycerol. The sphingosine and fatty acid can collectively be categorized as a ceramide.
And all the rest one is correct.
