Longitudinal waves

a. travel the fastest.

b. cannot be detected in locations between 105° and 140° from an earthquake's epicenter.

c. travel through solids and liquids.

d. All of the above.

I believe that the answer you seek is D all of the above. I could not find any information on B but I can confirm that these specific waves can travel through both forms of solid and liquid and also gas and travel faster then transverse waves.
