Answer:
The correct answer is option C.
Explanation:
The speed of the sound in the air at sea level is given as 1238 km/h.
1 km = 1000 m
1 hour = 3600 seconds
Speed of the sound in air at sea level can be written in meter per second as:
[tex]1238\times \frac{1000 m}{3600 s}=343.88 m/s\approx 343 m/s[/tex]
The nearest value of speed of sound from the given option is 330 m/s that option C.
