Which of the following is the best explanation of the difference between prejudice and discrimination?

Prejudice is a unjustified and baseless attitude towards an individual only because of his membership of a social group. (Ex. Sara likes Jessica because she is in the art club but she absolutely despises Jonah because he is in the math club). Discrimination refers to unjust or negative treatment of a person or a group from other people because he/she belongs to a particular class, group or category. (Ex. Sara invites Jessica to her party, but not Jonah)
