To determine which of the given options are saturated hydrocarbons, we first need to understand the definitions of the hydrocarbon types:

1. Alkanes: These are saturated hydrocarbons, meaning they contain only single bonds between carbon atoms. Their general formula is $C_nH_{2n+2}$.

2. Alkenes: These hydrocarbons contain at least one double bond and are considered unsaturated. Their general formula is $C_nH_{2n}$.

3. Alkynes: These hydrocarbons contain at least one triple bond, making them unsaturated as well. Their general formula is $C_nH_{2n-2}$.

Now we can analyze the options given:

1. A. Alkynes only: Incorrect, as alkynes are unsaturated.

2. B. Alkanes only: Correct, since alkanes are the only saturated hydrocarbons.

3. C. Alkanes and alkenes: Incorrect, as alkenes are unsaturated.

4. D. Alkenes and alkynes: Incorrect, as both are unsaturated.

Final Answer

B. Alkanes only
