Answer: The correct answer is Option C.
Explanation:
Speed of sound is directly related to the temperature.
The relation between speed of sound and temperature is given by the equation:
[tex]\text{Speed of sound}=331.5+0.60T(^oC)[/tex]
where, T = absolute temperature
Putting T = 56°C in above equation, we get:
[tex]\text{Speed of sound}=331.5+0.60\times 56=365.1m/s[/tex]
Hence, the correct option is Option C.
