The correct answer is - With full, red line.
The circum-pacific belt is represented with a full red line. The line marks all of the belt uninterruptedly, starting from New Zealand, through the islands of Southeast Asia, along the coast of East Asia, bellow the Bering Strait, and along the western coasts of North and South America, ending at Patagonia.
This line, roughly represents the tectonic plate boundaries of the Pacific plate with the other plates with which it is in contact, or rather getting submerged bellow them. Because the plate boundaries are convergent, with the Pacific plate submerging bellow the others, there's intense geologic activity, manifested through earthquakes, volcanic activity, tsunamis.
