Independence means that there is no relationship between the variables in the contingency table. Option A describes an interaction, Option B is not a relevant consideration, and Option C describes a situation where the observed frequencies do not match the expected frequencies under a certain distribution assumption (such as a chi-square test). Independence assumes the null hypothesis of no association between the variables, with the alternative hypothesis suggesting some form of dependence or relationship.
