Among the following compounds, the strongest acid is

Given data : It is given to identify among the following compounds, the strongest acid is, which option is correct

Explanation:
In acetylene, benzene, and ethane, the carbon atom is joined to another carbon atom. The carbon atom and oxygen atom are joined in methanol. Greater than that carbon, oxygen has a stronger electronegativity. In comparison to acetylene, benzene, and ethane, methanol is hence more electronegative. 

As a result, $C{H}_{3}OH$ is the most powerful acid.
Hence, the correct option (D).$C{H}_{3}OH$.
