Explanation:

"The distribution of volcanoes" - The distribution of volcanoes can be explained by the movement of tectonic plates. Volcanoes often occur at plate boundaries, where plates interact, such as subduction zones or divergent boundaries.

"Matching of the shorelines of continents" - The idea that the shorelines of continents fit together like pieces of a jigsaw puzzle supports the continental drift theory. This concept was a key piece of evidence used by Alfred Wegener, who proposed the theory.

Therefore, the correct option is 3, "Both 1 and 2."
