b : alfred wegener
c : isaac newton
d : johannes kepler

The correct answer is B. Alfred Wegener is the scientist who first proposed the existence of Pangaea and Panthalassa.

Explanation:

Alfred Wegener was a German astronomer and climatologist, best known for his theory of "continental drift" proposed in 1912 and published in 1915.

The theory of continental drift was based, among other things, on the way in which the shapes of the continents on each side of the Atlantic Ocean seemed to fit, like Africa and South America. It also took into account the distribution of certain geological formations and the fossil record of the northern continents, which stated that they could have shared floras and faunas in earlier geological times. With these data, Wegener calculated that the set of current continents were united in a remote past of the Earth, forming a supercontinent, called Pangea.
