c100°F
d75°F
eNone of the above/More than one of the above
Explanation
The relation between Celsius and Fahrenheit is given by the following formula— $$^{\circ}F = \frac{9}{5}^{\circ}C + 32$$ $$\Rightarrow ^{\circ}F \frac{9}{5} \times 50 + 32 = \frac{45^{\circ}}{5} + 32$$ $$= 90 + 32 = 122^{\circ}$$ Therefore, 50°C = 122°F on the Fahrenheit scale.
