The correct option is C Prejudice
Prejudice means to judge others negatively.
In our society, we associate certain qualities with people based on their caste or gender. This is called stereotyping. And from stereotyping emerge the prejudices.
One such stereotype is that women do not have a technical or scientific mind. Hence, there is a prejudice that girls cannot study certain subjects. Such negative judgements are baseless, and we must never believe in them.
