Symptoms of withdrawal from alcohol characterized by agitation, disorientation, hallucinations and/or delusions are termed:

A. delirium tremens (tremors) Delirium tremens (DTs) is a severe and potentially life-threatening form of alcohol withdrawal marked by hallucinations, confusion, agitation, and autonomic instability. B. regression Regression is a defense mechanism where the person reverts to earlier behaviors, not a withdrawal syndrome. C. dependence Dependence refers to the ongoing need for alcohol, not the withdrawal symptoms when use stops. D. cross-tolerance Cross-tolerance refers to the body's reduced response to one drug due to tolerance of another, not withdrawal.
