The correct option is C Tethys sea
Tethys Sea, former tropical body of salt water that separated the super continent of Laurasia in the north from Gondwana in the south during much of the Mesozoic era (251 to 65.5 million years ago). Laurasia consisted of what are now North America and the portion of Eurasia north of the Alpine-Himalayan mountain ranges, while Gondwana consisted of present-day South America, Africa, peninsular India, Australia, Antarctica and those Eurasian regions south of the Alpine-Himalayan chain. These mountains were created by continental collisions that eventually eliminated the sea. Thus, option C is correct.
