Does the position of the stretch of the oxygen-hydrogen bond in alcohols depend

Question

Does the position of the stretch of the oxygen-hydrogen bond in alcohols depend on the concentration of the alcohol?

A) No. the position of the stretch of the O-H bond depends on the strength of the O-H bond, but not the concentration of the alcohol.

B)Yes, the more concentrated the alcohol, the more likely it is for the alcohol to form intermolecular hydrogen bonding. So the OH group of a concentrated (hydrogen-bonded) solution absorbs at a lower wavenumber than that of the diluted solution.

I got 2 answers to ths question. Can you tell me which answer is correct please? Thanks.

Explanation / Answer

Ans B is correct where conc alcohol solution is more towards forming hydrogen bonding among themselves and there weakening the OH bond strength and absorbing at lower wavelenghths.
