The diagram shows a simple lipid. what type of lipid is shown? saturated unsaturated phospholipid triglyceride

The correct answer is option A, that is, saturated.

The mentioned lipid is not a phospholipid, as it does not comprise a phosphate group at the terminal of the chain, and is not a triglyceride due to the absence of glycerol moiety.

Each carbon combined with the hydrogens forms the maximum number of possible C-H bonds, thus, there are no multiple bonds between the carbons. Hence, it can be concluded that the lipid is saturated.
