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
