Some of the most typical characteristics of groundwater are weak turbidity, a constant temperature and chemical composition and almost overall absence of oxygen. Circulating groundwater can have extreme variation in the composition with the appearance of pollutants and various contaminants.
I think that it would still just be an island. A peninsula is a landform surrounded by water that extends outward from the land. Imagine a green rectangle sticking out from the green oval you pictured. That rectangle would represent the peninsula. Therefore, dividing the island in half would not create any peninsulas.

The correct answer is C. Point C
Explanation
The image is a map that shows Antarctica and the areas of the American continent, Africa, and Oceania that was attached to it during the time of Pangea. It also shows a white zone of influence of the glacial in the other continents and arrows that inform where they moved. According to the movement expressed by these arrows, the point that was probably closest to the South Pole (Antarctica) at the time of Pangea is point C because on the map it can be seen that it has already moved and is still attached to the South Pole. Furthermore, points A, B, and D. are much further from the south pole than the others.
