Which one of the following is located at the southernmost latitude ?

To determine the southernmost location, we compare the latitudes of the southernmost points of each region. Chile's territory extends to Cape Horn, located at approximately 55°58′S in the Tierra del Fuego archipelago [1]. In contrast, Australia's southernmost point (including Tasmania) is South East Cape at roughly 43°38′S [1]. South Africa's southernmost point is Cape Agulhas, situated at approximately 34°50′S [1]. Polynesia includes New Zealand, whose southernmost point (South Cape on Stewart Island) is at roughly 47°17′S [1]. Geographically, Chile reaches significantly further south toward Antarctica than the other options, as it is part of the Antarctic floral kingdom stretching into the higher latitudes of the Southern Hemisphere [2]. Therefore, Chile is located at the southernmost latitude among the choices provided.
