What to do when scholars are divided on an opinion?

I wanted to know what to do when scholars are divided on an opinion? Sometimes whenever I search whether a thing is halal or haram, scholars are divided on the opinion, some say it's halal, some say it's makrooh and some says it's haram, so what should we do in this situation? Should we go with the choice which is most suitable for us? And will that person be punished if an action was haram to do
