A man has been arrested for driving under the influence twice within the past year. He continues to drink alcohol, and he tells his friends he does not have any issues with alcohol consumption. What is this behavior an example of?

Choice A reason: Sublimation is a defense mechanism where unacceptable impulses are transformed into socially acceptable actions. For example, channeling aggression into sports. It does not apply to ignoring substance-related consequences. Choice B reason: Denial is the refusal to acknowledge reality or facts, especially when they are distressing. In this case, the man denies having a problem despite legal consequences and continued risky behavior, making denial the most accurate descriptor. Choice C reason: Reaction formation involves expressing the opposite of one's true feelings, often unconsciously. For example, treating someone you dislike with excessive kindness. It does not fit the scenario of ignoring substance abuse. Choice D reason: Repression involves unconsciously blocking distressing thoughts or memories. It is not the same as consciously denying a problem, which is what this man is doing.
