Consider the following statements regarding continental drift theory:1...
Explanation:

1. Statement 1:
The statement is incorrect. The continental drift theory was actually proposed by Alfred Wegener in 1912, not Arthur Holmes.

2. Statement 2:
This statement is correct. According to the continental drift theory, all the continents were once part of a single supercontinent called Pangaea, surrounded by a mega ocean known as Panthalassa. Over time, the continents drifted apart to their current positions.

3. Statement 3:
This statement is correct. One of the criticisms of the continental drift theory was that it did not provide a satisfactory explanation for the forces driving the movement of the continents. It wasn't until the development of the theory of plate tectonics in the 1960s that a mechanism for continental drift was proposed, involving the movement of rigid lithospheric plates over the semi-fluid asthenosphere.
Therefore, the correct answer is option 'C', as statement 2 is correct while statements 1 and 3 are incorrect.
