Answer : The correct option is, tranverse wave.
Explanation :
Longitudinal waves : It is defined as the waves in which the particles of the medium move in the direction of the wave.
Transverse wave : It is defined as the waves in which the particles of the medium travel perpendicularly to the direction of the wave.
Surface wave : It is defined as a combination of transverse and longitudinal waves.
Mechanical waves : These are the waves that require a medium to travel so that they can transport their energy from one location to another.
For Example: Sound waves, surface wave.
From this conclude that, tranverse wave has a wave perpendicular to the disturbance.
Hence, the correct option is, tranverse wave.
