Solution

The correct option is A
1 only
Explanation:

Statement 1 is correct: According to Wegener, the proponent of continental drift, all the continents formed a single continental mass, a mega ocean surrounded by the same. The super continent was named PANGAEA, which meant all earth.

Statement 2 is incorrect: The mega-ocean was called PANTHALASSA, meaning all water.
Wegener proposed that the movement accountable for the drifting of the continents was instigated by tidal force and pole-fleeing force.

Statement 3 is incorrect: Coriolis force had existed ever since earth started rotating.
