A)-10 $\circ$ C
B)0 $\circ$ C
C)10 $\circ$ C
D)20 $\circ$ C
E)30 $\circ$ C

The speed of sound in air increases by approximately 0.6 m/s for every degree Celsius increase in temperature. Given that the speed of sound at 0°C is 331 m/s and at the unknown temperature it is 343 m/s, the difference is 12 m/s. Dividing the difference by the rate of increase (0.6 m/s/°C) gives 20°C, which corresponds to choice D.
