Answer : Saturated hydrocarbons contain carbon and hydrogen atoms that have 1 bond.
Explanation :
Hydrocarbon : It is an organic compound that contains only hydrogen and the carbon atoms.
They are of two types which are saturated hydrocarbon and unsaturated hydrocarbon.
Saturated hydrocarbons : It is defined as the hydrocarbons in which a single bond is present between the carbon-carbon atoms. The general formula for these hydrocarbons is

Unsaturated hydrocarbons : It is defined as the hydrocarbons which have double or triple covalent C-C bonds. They are known as alkenes and alkynes respectively. The general formula for these hydrocarbons is
and

Hence, from this we conclude that the saturated hydrocarbon contains 1 bond between the carbon and hydrogen atoms.
