The correct answer is "The study of human cultures." Anthropology is a field of study that focuses on understanding human cultures, including their social structures, beliefs, customs, and behaviors. It involves examining various aspects of human life, such as language, art, religion, and technology, in order to gain insights into the diversity and complexity of human societies throughout history and across different geographical regions. Through anthropological research and analysis, scholars aim to uncover universal patterns, as well as unique cultural practices, and contribute to a deeper understanding of what it means to be human.
