C Correct answer
Explanation

The Fahrenheit and Celsius scales meet at -40 degrees. Using the conversion formula F = (9/5)C + 32, we set x = (9/5)x + 32. Solving: x - (9/5)x = 32, so (-4/5)x = 32, and x = -40. At -40°F = -40°C. Options A (0), B (32 - the freezing point of water in °F), and D (21.6) are all incorrect.
