What do ocean waves and sound waves have in common?
a. both are transverse waves. b. both are longitudinal waves
c. both are electromagnetic waves.
d. both exhibit the same particle-to-particle interaction.
e. both are mechanical waves.

Ocean waves and sound waves are : mechanical wave. A and B aren't right at all. and C is  wrong because they aren't electromagnetic.
Mechanical wave is a wave that is an oscillation of matter, and therefore transfers energy through a medium.

Hope this help
