In 1596, who suggested in his work ‘Thesaurus Geographicus' that the continents of the earth were not always located in their present positions?

The correct answer is Abraham Ortelius.

Abraham Ortelius was a Dutch cartographer and geographer, best known for creating the first modern world atlas, the Theatrum Orbis Terrarum (Theatre of the World), in 1570.
In 1596, Ortelius published his work Thesaurus Geographicus. In this work, he observed the similarity in the outlines of the coastlines of the Americas, Europe, and Africa. He suggested that the Americas were "torn away from Europe and Africa... by earthquakes and floods" and went on to propose that the continents of the Earth were not always located in their present positions, foreshadowing the modern theory of continental drift.
