The estimated number of cells in the human body is 50 to 100 trillion. This includes all types of cells, such as muscle cells, nerve cells, and blood cells. Option A (3.2 billion) is closer to the estimated number of base pairs in the human genome, while options B (20,600) and D (10 to 100 million) are too small to be the number of cells in the body.
