1. A.A primarily impulse-control problem caused by poor inhibitory control and sensation seeking, with urges that are not mainly shaped by reinforcement
2. B.An obsessive-compulsive pattern in which buying acts are performed mainly to neutralize intrusive obsessions (for example, contamination or harm-related thoughts)
3. C.A reinforcement-maintained behavior pattern (behavioral addiction cycle) in which buying is strengthened by reward and/or short-term relief from negative affect
4. D.A pattern best explained by stable personality traits (for example, materialism or low conscientiousness) rather than learning and reinforcement processes

CBT and learning-theory formulations emphasize functional relationships: behaviors persist when they are reinforced. Compulsive buying is commonly described as continuing because it produces immediate reward (excitement, pleasure, social validation) and/or reduces distress (temporary relief from anxiety, sadness, tension), which increases the likelihood of repeated buying despite longer-term negative consequences. The choices describing an impulse-control deficit, an OCD-neutralizing compulsion, or a primarily trait-based explanation can appear in other frameworks, but they do not match the core learning-theory/CBT emphasis on operant reinforcement maintaining the behavior.
