Sam and Travis Spar with Each Other in the Kickboxing

Sam and Travis spar with each other in the kickboxing gym. Often, when Travis throws a jab, he is punished with a left hook from Sam. For the next several rounds, he keeps his distance from Sam, but eventually learns to close in and fight while avoiding throwing the jab. Which analysis below fits Travis' behavior?

A) His initial suppression of jab throwing was due to R-O associations, but ultimately he formed an S-O association.
B) His avoidance of Sam was due to R-O learning, and his learning to avoid throwing the jab was S-O.
C) His tendency to keep his distance from Sam, and then later to fight but avoid throwing the jab, suggests that S-O learning was easier or faster than R-O learning.
D) Fear produced analgesia so that the left-hook was less effective, as the perceptual-defense-recuperative model would predict.
