The correct answer is A. look.

A look is a brief glance, while a peep is a quick, furtive look. A sight is something that is seen, and a gaze is a long, steady look. In the context of the question, “One look and you know who among them is the culprit,” the word “look” is the most appropriate choice because it suggests a quick, but accurate, assessment of the situation.

  • B. Peep. A peep is a quick, furtive look. It is often used to spy on someone or something. In the context of the question, “One look and you know who among them is the culprit,” the word “peep” is not the most appropriate choice because it suggests a secretive or suspicious look.
