Answer

Brief Explanations:

To determine when Earth’s landmasses became recognizable as today’s continents, we refer to geological knowledge. The breakup of the supercontinent Pangaea led to the formation of modern - like continents. Around 135 million years ago, the landmasses had evolved to a state where they resembled the continents we know now. 10 million years ago is too recent, 180 million years ago is during the earlier stages of Pangaea's breakup (not yet like modern continents), and 300 million years ago is when Pangaea was more intact.

Answer:

B. 135 million years ago
