A Banksy mural of _____ is to be removed from London High Court.

The answer is a Banksy mural of a judge beating a protestor, which aligns with the artist's history of addressing social and political issues through provocative public art. This particular mural likely critiques the relationship between the legal system and protests, suggesting a commentary on authority and the justice system's treatment of dissent. Banksy's work often reflects current events and societal tensions, bringing attention to topics like injustice, oppression, and the power dynamics in society, which is consistent with his previous pieces. The other options, while they may represent various social themes, do not match the specific context of a Banksy mural that has garnered attention for its controversial nature and relevance to ongoing legal and societal discussions in London.
