The correct answer is A.
By trying out the equipment first at a fitness club you can make an informed decision as to whether you will use the equipment at home, if you are able to use the equipment, if you will get any benefit from it, if you enjoy using it. You don't want to make an unnecessary purchase of a piece of equipment you will never use and waste your money.
A chemical need for alcohol is an addiction, or alcoholism.
The most clear way would be - "Sam, I don't think stealing things from a shop is ok, it's illegal and you're stealing away the hard work of some people without paying for it".
That should send Sam a clear message that will explain him why stealing is wrong and why he shouldn't be tealing in the first place.
Its most definitely A, hope this helps :)
