Due to the variation of the motion of the molecules of air with temperature, the velocity of sound in the air is altered with temperature.
The simplified expression for the calculation of the speed of sound at a given temperature:
v = 331 + 0.6T
v = 331 + 0.6(50)
v = 361 m/s

The correct answer is C.
