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."
