C Correct answer
Explanation

Demographers estimate that approximately 0.1% (or about 6-7% in decimal terms) of all humans who have ever lived are currently alive. This is because human population has grown exponentially, and the vast majority of humans who ever lived lived in earlier centuries with much smaller populations. Current population represents a tiny fraction of cumulative human history.
