Final Answer :
A
Explanation :
The pH of a solution is calculated using the formula pH = -log[H+], where [H+] is the concentration of hydrogen ions. Given [H+] = 1.00 × 10^-7, the pH = -log(1.00 × 10^-7) = 7. This is because the pH scale is logarithmic, and a hydrogen ion concentration of 10^-7 M corresponds directly to a neutral pH of 7.
