The pH scale ranges from:

0-100
1-10
0-14
0-7

The correct answer is: 0-14

The pH scale measures the acidity or basicity of a solution on a scale of 0-14, with 7 being neutral. Option A and B are incorrect because the pH scale does not have a maximum value of 100 or 10. Option D is incorrect because it only represents the acidic end of the scale and does not account for basic solutions. Therefore, the correct answer is option C.
