The correct answer is (a) 330 m/s.
However, the speed of sound in air varies at different ambient temperatures.
At room temperature, due to faster vibration of molecules( as they possess greater energy), sound waves travel faster ( approximately 346 m/s).
At freezing temperatures, it slows down and travels at 330 m/s.
The speed of sound also gets affected by other external factors such as humidity, air pressure, etc.
