Answer : 
Saturated hydrocarbon : 3-methyloctane, propane, heptane.
Unsaturated hydrocarbon : cyclopentene, heptyne
Explanation : 
Saturated hydrocarbon : These are those hydrocarbons in which all carbon atoms and hydrogen atoms are bonded together with single bonds.
For example : Methane, Ethane, etc.
Unsaturated hydrocarbon : These are those hydrocarbons in which carbon-carbon atom bonded together with double or triple covalent bonds. 
For example : Ethene, Butyne, etc.
Therefore, the saturated and unsaturated hydrocarbons are:
Saturated hydrocarbon : 3-methyloctane, propane, heptane.
Unsaturated hydrocarbon : cyclopentene, heptyne
