• A. 32 °C
• B. 5.6 °C
• C. 42 °C
• D. 15.6 °C

Answer: (B)

Verified step by step guidance

1. Recall the formula to convert Fahrenheit (F) to Celsius (C): \( C = \frac{5}{9} (F - 32) \).
2. Substitute the given Fahrenheit temperature (42 °F) into the formula: \( C = \frac{5}{9} (42 - 32) \).
3. Calculate the difference inside the parentheses: \( 42 - 32 = 10 \).
4. Multiply the difference by 5 and then divide by 9: \( C = \frac{5}{9} \times 10 \).
5. Simplify the expression to find the temperature in degrees Celsius.
