Which pH range is base?

Explanation:
Base (alkaline) means a pH above 7 on the pH scale, which runs from 0 to 14. Values below 7 are acidic, 7 is neutral, and values above 7 indicate basic conditions. So the range that represents bases is from 7 up to 14. This is why the 7-14 range is the correct choice. The other options mix in acidic ranges (below 7) or treat neutral as a separate point rather than showing the basic side of the scale. In HazMat contexts, recognizing bases helps predict corrosivity and how a substance will react with materials and other chemicals.
