You are correct, stained fingernails can be a sign of long-term tobacco use. I apologize for the incorrect answer in my previous response. Thank you for clarifying.

To determine the sign of long-term tobacco use, we need to analyze each option and identify the one that is commonly associated with tobacco use over an extended period of time.

A. Acne: Acne is not typically considered a direct sign of long-term tobacco use. It is more commonly associated with hormonal changes during puberty.

B. Stained fingernails: Stained fingernails can be a potential sign of long-term tobacco use. Tobacco contains numerous chemicals that can yellow the nails over time due to repeated exposure.

C. Hair loss: Hair loss is not specifically linked with long-term tobacco use. Hair loss can have several causes, including genetics, age, hormonal changes, and underlying health conditions.

D. Weight gain: Weight gain is not generally associated with long-term tobacco use. Some individuals may gain weight when quitting tobacco due to increased appetite or changes in metabolism, but it is not a direct sign of long-term tobacco use itself.

Based on these explanations, the option that best represents a sign of long-term tobacco use is B. Stained fingernails.
