The correct answer would be Stigma. Stigma refers to characteristics of people that are considered socially unacceptable, for example, mental illness, disabilities or scars.

Explanation:

Stigma is basically a mark of disgust or disgrace which is associated with a specific circumstance, quality or a person. In simple words, we can say that stigma is a bad quality associated with someone or something which make it disgusted. For example a television is not getting work due to his past drinking habit, which means his drinking habit has become his stigma. Any scar on a clear clean skin of a person can also be called as a stigma. A person with a mental ailment is also considered having a stigma. So all such things that are not easily socially acceptable are called as stigma.
