If an employee maintains respectful language with a customer even under stress, which combination is shown?

Correct answer: Stress management and etiquette

The direct answer is D: stress management and etiquette. A stressed employee may feel pressure, irritation, or tiredness, but professional behaviour requires controlling the reaction and speaking respectfully to the customer. Stress management is the ability to handle pressure without losing control. Etiquette means polite, considerate, and appropriate conduct. Option D includes both qualities, so it is correct. Option A, only formality, is too narrow: the behaviour shows emotional control as well as polite language. Option B, personal pressure, describes the employee’s condition, not the skill demonstrated in the interaction. Option C, improper silence, is incorrect because respectful communication is not the same as refusing to speak. The employee can remain calm, listen, use courteous words, explain the matter clearly, and seek help if needed. Respect should not disappear merely because the situation is difficult. Memory cue: pressure outside, courtesy inside—this is professional self-control.
