Step-by-step explanation:
The subject of this question falls under Social Studies as it deals with political beliefs and voting preferences. A person who is described as a black female with an income of $100k per year and votes for less small business regulation but votes to have social media banned for children under the age of 16 can be seen as having a complex set of beliefs and preferences. This person values economic freedom by supporting less regulation for small businesses, which aligns with ideas typically associated with conservatives. However, their support for banning social media for children under 16 could resonate with liberals who prioritize protecting children and regulating media consumption.
