The correct answer is - d. all of the above.
The movement of the continents plays a very important role in the global climate patters. The movement of the continents, their location on the globe, creating mountain ranges, are all factors that have very big importance in the creation of the climate.
For example:
If the continents moved in a way that none of them has land mass on or in close proximity to the poles, it will shape the climate in a way where it will be much more humid, with more precipitation, and the world will be dominated by tropical rainforests.
But, that is a scenario where the continents are not merged. If they move in the manner that they all merge, than only the coastal regions will be like that, while the interior will be occupied by vast, hot, dry deserts because it will be too far away from the influence of the oceans.
And of course we have the mountains. If there isn't mountains in a certain, place, it means that the air masses can easily pass through, but if there is, than they will be stopped, and will influence only the part to which the mountains are, but on the other side of them, thy will have little to no influence.
