Official Solution & Explanation:
Correct Answer: Option C(केल्विन)
केल्विन पैमाने (Kelvin Scale) पर ऋणात्मक मान नहीं होता है, क्योंकि इसका न्यूनतम संभव मान परम शून्य ($0 \text{ K} = -273.15^\circ\text{C}$) होता है।
The Kelvin scale is an absolute temperature scale whose lowest possible value is absolute zero ($0 \text{ K}$), hence it cannot have negative values.
