Which choice best describes data in the graph that support Liu et al.'s conclusion?
CrCoNi outperformed CrMnFeCoNi at 20 kelvins in both initiation toughness and propagation toughness even though it is composed of fewer elements.
A
Both CrMnFeCoNi and CrCoNi showed substantially higher propagation toughness than initiation toughness throughout the range from 20 kelvins to 293 kelvins.
B
The changes in initiation toughness and propagation toughness were greater between 20 kelvins and 77 kelvins than between 77 kelvins and 198 kelvins for both CrMnFeCoNi and CrCoNi.
C
For both CrMnFeCoNi and CrCoNi, initiation toughness and propagation toughness were lower at 293 kelvins than at 20 kelvins.
D
