Which of the following groups would be found on an alcohol molecule?

I’ve answered this question before so if these are the choices to the question presented:

An oxygen atom double-bonded to a carbon atom, with a hydrogen atom single-bonded to the same carbon atom. 

A hydrogen atom covalently bonded to an oxygen atom, which is covalently bonded to a carbon in the carbon chain. 

A carbon atom single-bonded between two other carbon atoms, with an oxygen atom double-bonded to the central carbon atom as well. 

An oxygen atom single-bonded between two carbon atoms within a carbon chain. 

Then, the answer would be “a hydrogen atom covalently bonded to an oxygen atom, which is covalently bonded to a carbon in the carbon chain.”

the answer to your question is c.
