The relationship between temperature changes on Celsius and Fahrenheit scales is given by $$ \Delta F = \frac{9}{5} \Delta C $$. If the change in Celsius is $$\Delta C = 40°C$$, substituting this into the equation yields

$$ \Delta F = \frac{9}{5} \times 40 = 72°F $$. Therefore, the correct answer is Option 3: 72°F.
