Fossils, like the mesosaurus found on both africa and south america and the glossopteris plant found on several continents, to support the dinosaur era continental drift theory wegener theory plate tectonic theony

Option B, continental drift theory

Explanation:

Through the evidences collated from the fossils it was established that the continents were joined in the past. Or else if they were not joined there are high possibilities that the species might have evolved on two separate land mass thereby contradicting the Darwins’s theory.  

Mesosaurus is a species of crocodile which is unable to swim and in this scenario if both the continents of Africa and South America have traces of Mesosaurus then it is clear that both these continents were joined once or else swimming from one continent to other is a “no’no” case.
