Completely removing a reinforcement for a behavior defines the technique of behavior modification. a. avoidance b. aversion c. command-response-reward d. extinction

d. extinction

Explanation:

The extinction technique refers to the elimination of a reinforcerment for a behavior in order to eliminate that problematic behavior, for example when kids throw toys into the ground to get attention from their parents, this is at first good because the kid gets the attention needed, but they will keep throwing the toy to the ground cause it gets them what they want, so if the mom stops picking it up and giving it back or giving them attention, the kid will stop throwing it, by eliminating the reinforcement "the attention", the kid stops the undesired behavior "throwing the toy to the ground".
