What does raising both shoulders generally indicate?

Correct answer: Lack of knowledge or uncertainty

Raising both shoulders is commonly called a shrug, an important example of non-verbal communication. A shrug often communicates uncertainty, doubt, or that the person does not know the answer; therefore, option B is correct. It does not normally express a definite answer or victory. Anger may involve tense muscles or an intense facial expression, but a simple shrug most commonly suggests uncertainty in this context.
