Final answer:
The question involves determining the identity of a figure related to racial identity and ancestry. Rachel Dolezal is the correct answer; she identified as black despite having genetically white parents.
Step-by-step explanation:
The question relates to a scenario where someone's racial identity is legally defined by genetic ancestry. In the United States, historically, black people have often been defined by 'blood laws', which have lingering effects on how racial identity is viewed today. A contemporary example is Barack Obama, who, despite being of mixed European and African ancestry, is often simply considered black. Another case is Tiger Woods, who invented the term Cablinasian to represent his Caucasian, Black, American Indian, and Asian heritage, yet is predominantly seen as black in America and as Thai in Thailand. This highlights how societal perceptions can override an individual's self-identification.
The correct answer to the given question is A. Rachel Dolezal. She was a notable figure who was born to white parents but self-identified and was culturally accepted as black until her ancestry was publicly challenged.
