Question

which coastlines most closely match each other and are, therefore, used as evidence to support wegeners theory?
india and eurasia
australia and africa
africa and south america
australia and north america

Explanation:

The question is about matching coastlines to support Wegener's theory (continental drift). The coastlines of Africa and South America fit together like puzzle pieces, a key piece of evidence for continental drift. Other pairs (India - Eurasia is about collision, Australia - Africa, Australia - North America don't have the same fit as Africa - South America).

Answer:

C. Africa and South America
