The example of a hereditary risk factor from your list is having fair skin that is prone to sunburn. This trait can be influenced by genetic factors inherited from one's parents. The other options — smoking, eating junk food every day, and being a couch potato — are primarily related to lifestyle choices rather than hereditary factors.
