Which one of the followingstatements is true ?

The relationship between Celsius (C) and Fahrenheit (F) scales is defined by the formula F = (C × 9/5) + 32 [t2][t4]. This implies that a change in temperature (ΔT) follows the ratio ΔF = ΔC × 1.8 [t3][t9]. Therefore, a difference of 10° on the Celsius scale corresponds to a difference of 18° on the Fahrenheit scale (10 × 1.8 = 18), making option 3 correct [t6][t9]. Option 1 is incorrect because a 25°F difference equals approximately 13.89°C (25 ÷ 1.8). Option 2 is false as 0°F converts to approximately -17.78°C [t5]. Option 4 is incorrect because 202°F converts to approximately 94.4°C using the formula (202 - 32) × 5/9 [t1][t8], meaning 202°F is actually warmer than 90°C.
