Explanation:

Hydrocarbons are organic compounds composed only of carbon and hydrogen atoms. We analyze each option:

1. $\text{CH}_2\text{O}$ contains oxygen, so it is not a hydrocarbon.
2. $\text{HCOOH}$ contains oxygen, so it is not a hydrocarbon.
3. $\text{CH}_3\text{OH}$ contains oxygen, so it is not a hydrocarbon.
4. $\text{CH}_4$ is made up solely of carbon and hydrogen, fitting the definition of a hydrocarbon.

Answer:

D. $\text{CH}_4$
