Final answer:
To convert 40 ⁰C to ⁰F, use the formula F = (C × 9/5) + 32, resulting in 104 ⁰F.
Step-by-step explanation:
To convert Celsius (⁰C) to Fahrenheit (⁰F), you can use the formula F = (C × 9/5) + 32. For the given temperature of 40 ⁰C, we can substitute it into the formula: F = (40 × 9/5) + 32 = 104 ⁰F. Therefore, the correct answer is D. 104.
