Final answer:
Criticizing Linda in front of her colleagues is an example of punishment and represents an informal negative sanction that discourages undesirable behavior.
Step-by-step explanation:
Jorge wants to motivate Linda to stop taking overly long lunch breaks. An example of punishment in this scenario would be c) Criticizing Linda in front of her colleagues. This represents a form of informal negative sanctions, which are actions taken to punish or discourage behaviors that are considered undesirable within a social or workplace setting. In contrast, giving Linda a bonus for shorter breaks would be considered an informal positive sanction, as it encourages the desired behavior through rewards. Ignoring Linda's behavior is not a form of punishment or sanction, and allowing her to leave work early would likely be perceived as a reward, which could inadvertently reinforce the long lunch breaks rather than discourage them.
