Answer:
If the temperature increases, The speed of the wave will increase.
Explanation:
Longitudinal waves re the waves that require a medium to travel in. They are also a form of energy. Temperature is a common factor that affects the speed of longitudinal waves. Heat, like sound, is a form of kinetic energy. Molecules at higher temperatures have more kinetic energy, so they can vibrate faster. Since the molecules vibrate faster, longitudinal waves can travel more quickly hence option B is the correct answer.
