Correct answer: C. Either A. or B.
- A. Weight
- B. Volume
- C. Either A. or B.
- D. Neither A. nor B.
Explanation
Specific surface area may be expressed per unit mass or per unit volume, depending on whether a mass-based or volume-based definition is used. Therefore, both weight and volume are valid bases.
