Question

The Pacific Plate, which drives much of the tectonic activity in the Ring of Fire, is cooling off. Scientists have discovered that the youngest parts (about 2 million years old) are cooling off, contracting faster than the older parts of the plate (about 100 million years old.) The younger parts of the plate are the most active parts of the Ring of Fire.
What idea is the BEST supported by this paragraph?
(a)Movement from the contraction of the cool plates is contributing to tectonic activity in the Ring of Fire.
(b)the youngest parts of the plates will stay very cool completely and stop their tectonic activity.
(c)Most older parts of the Ring of Fire have stopped and will soon cool completely and stop their tectonic activity.
(d)The pacific plate has both the oldest and the youngest active volcanoes in the entire world.
