Explanation:

In grammar, a possessive noun is a type of noun that expresses possession or relationship, this is mainly formed in singular nouns by adding an apostrophe (') followed by an s or just an apostrophe if the noun ends in "s". According to this, the only option that contains a singular possessive noun and that uses correctly the possessive form is "Snowboarding is a family affair in Hannah Teter's family, which includes her siblings and parents" because in this the noun "Hanna Teter's" is singular and acts as a possessive noun owning "family"; also this is the correct way of making the noun possessive and this is the only noun that needs to be possessive in the sentence as other elements in the sentence do not express possesion.
