Would you please solve it real quick, that will be helpful and appreciated. Thank you. I will give you a good feedback too.

The mathematical forms for the three sinusoidal traveling waves are gives by wave 1: y(x, t) =(2 cm) sin (3x - 6t) wave 2: y(x, t) =(3 cm) sin (4x - 12t) wave 3: y(x, t) =(4 cm) sin (5x - 11t) where x is in meters and t is in seconds. Of these waves (choose one answer carefully, no partial credit): (a) wave 2 has the greatest wave speed and wave 3 has the greatest maximum transverse string speed (b) wave 1 has the greatest wave speed and also the greatest maximum transverse string speed (c) wave 2 has the greatest wave speed and wave 1 has the greatest maximum transverse string speed (d) wave 3 has the greatest wave speed and also the greatest maximum transverse string speed (e) wave 3 has the greatest wave speed and wave 2 has the greatest maximum transverse string speed
