To map Earth's interior, geologists use a network of seismometers to chart seismic waves that originate in the earth's crust and ricochet around its interior, most rapidly traveling through cold, dense regions and slower through hotter rocks.

(B) interior, which travel most rapidly through cold, dense regions, and more slowly
(C) interior, traveling most rapidly through cold, dense regions and more slowly
(D) interior and most rapidly travel through cold, dense regions, and slower
(E) interior and that travel most rapidly through cold, dense regions and slower
OG解释
This sentence explains in detail an activity of geologists (using seismometers to chart waves), focusing primarily on the object, seismic waves. A description of these waves is developed in a relative clause (that originate ... hotter rocks) that contains a compound verb phrase (originate ... ricochet . .). The action, ricochet, is further described in a participial phrase in which traveling ... is then further described in a comparison of travel speeds in cold and hot regions of Earth's crust.
C Correct. The modifiers are parallel and correctly positioned in relation to the verb.
