The correct answer is: $-4\text{ °F}$

Explanation

To convert Celsius to Fahrenheit use the formula $F = C \times \frac{9}{5} + 32$.

Steps:

  1. Formula: $$F = C \times \frac{9}{5} + 32$$
  2. Substitute $C = -20$: $$F = -20 \times \frac{9}{5} + 32$$
  3. Compute: $$F = -36 + 32 = -4\text{ °F}$$

Therefore, $-20^\circ\text{C}$ equals $-4\text{ °F}$.
