Answer: (B)

Verified step by step guidance

1. Recall the formula to convert Fahrenheit (°F) to Celsius (°C): \(\displaystyle C = \frac{5}{9} (F - 32)\).
2. Substitute the given temperature in Fahrenheit, which is 50°F, into the formula: \(\displaystyle C = \frac{5}{9} (50 - 32)\).
3. Calculate the difference inside the parentheses: \$50 - 32 = 18$.
4. Multiply 18 by 5/9 to find the Celsius equivalent: \(\displaystyle C = \frac{5}{9} \times 18\).
5. Simplify the multiplication to find the temperature in Celsius and compare it to the given options to identify which one matches.
