Answer:

C. could not provide a mechanism for moving continents

Explanation:

Without the discovery of magnetic reversals recorded on the ocean floor, scientists  could not provide a mechanism for moving continents.

Magnetic reversals are responsible for geological shifts and depend on the distribution of tectonic plates that causes movements of continents.

Asymmetric movement of tectonic plates leads to movement of continents  and the degree of asymmetry varies with the same rythm of the magnetic reversal rate.

Hence, discovery of magnetic reversals are important to identify the mechanism for moving continents.
