Who is revealed to be Vincent's younger detective brother?

In the context of the story, Vincent's younger brother, who is also a detective, is named Anton. This distinction is important as it highlights the contrasting paths the two brothers took in their lives. Vincent, a genetically inferior individual, struggles against a society that judges people based on their DNA, while Anton, being genetically engineered, represents the societal expectations of success and achievement. The revelation of Anton as Vincent's brother serves to deepen the themes of identity and the complexities of familial relationships within the narrative.

The other names listed do not correspond to characters in the story, making Anton the only correct answer. This also emphasizes the significance of familial ties in the film, particularly how Vincent's relationship with Anton impacts his journey and underscores the overarching messages about genetic discrimination and personal ambition.
