# Selection of parent carbon chain for IUPAC naming [closed]

How to select the parent carbon chain for IUPAC naming of following compound?

I think the red numbering is correct, but in the answer key, they have used the blue numbering.

Which is correct?

My question is regarding selection of parent chain in an alcohol. While selecting the parent carbon chain (base name) to write the IUPAC name of an alcohol, do we have to give preference to the one which gives the lowest locant to the $$\ce{–OH}$$ group (viz. primary functional group here), or the one which has the maximum number of carbon atoms?
