Answer
A saturated hydrocarbon is characterized by having only single bonds between carbon atoms and maximizes the number of hydrogen atoms attached. The general formula for saturated hydrocarbons, known as alkanes, is CnH2n+2.

Answer
C4H6: This has two less hydrogens than expected (for C4, it would be 10).
C4H8: This has the right number of hydrogens (10 for 4 carbons, which means it can be a saturated hydrocarbon).
C5H12: This also fits the formula (12 hydrogens for 5 carbons). It is a saturated hydrocarbon.
C8H10: This has four less hydrogens than expected, indicating unsaturation.
Thus, the only options that represent saturated hydrocarbons are C4H8 and C5H12.
