86.To map Earth’s interior, geologists use a network ofseismometers to chart seismic waves that originate in the earth’s crust andricochet around its interior, most rapidly traveling through cold, denseregions and slower through hotter rocks. C

(A) interior, most rapidly traveling throughcold, dense regions and slower

(B) interior, which travel most rapidlythrough cold, dense regions, and more slowly

(C) interior, traveling most rapidly throughcold, dense regions and more slowly

(D) interior and most rapidly travel throughcold, dense regions, and slower

(E) interior and that travel most rapidlythrough cold, dense regions and slower

看了一些解答，travelling修饰ricochet，那是说ing可以修饰从句中的动词？这个句子成分，我理解为geologist use seismometers to chart waves that originate... and (that) ricochet...,traveling...

originate和ricochet平行，修饰waves，不知道这个理解对不对

求大神指教，非常感谢！马上就要考试了，很焦虑
