The most accurate statement regarding racial distinctions among people is:
"Race is a social classification based on physical characteristics that do not identify differences in people."
This reflects the understanding that while race is often perceived in terms of physical traits, it is primarily a social construct rather than a biologically significant category. Biological research has shown that the genetic differences within so-called racial groups are often greater than those between them, and race does not have a valid basis in biology. Instead, it is shaped by historical, social, and cultural contexts.
