We see that this is a region near the continents, so it is probable that there is the boundary of a tectonic plates around there. Since there are islands there, it is quite probable that there is a subduction zone near them which means that the oceanic crust is going below the continental one and the continental is slowly elevated. This also shows that the boundary is convergent, since transform boundaries do not lead to elevation. Near convergent boundaries, there are frequently volcanoes and shallow earthquakes. Finally, the climate near Alaska is cold and this does not depend on whether islands are near a boundary or not. So, 2 4 and 5 are correct.
