B. P waves can travel through liquids
Explanation:
P waves or primary waves are elastic waves produced from an earthquake. They are the first waves that arrives a Seismic station when an earthquake disturbs the earth.
P and S waves are both body waves that moves within the earth.
P- waves travel faster than S- waves and can propagate through any medium. S-waves or Secondary waves are shear waves that can only propagate through soilds.
Both waves are longitudinal and moves parallel to their source of propagation. They move by disturbing other particles in their line.
Transverse waves are the love and rayleigh waves. They are both surface waves that travels and cause disturbance on the surface of the earth during an earthquake. They move up and down.

When a species is classified as threatened, it means that that particular species is expected to become endangered, not extinct. The species that are threatened, are species that have experienced a significant drop in numbers in recent times, but still have enough individuals to be able to survive and keep the species going. But if the situation starts to become worse and the species continues to lose numbers, than the species will fall into the category of endangered species, which will mean that it is expected that the species will die out in the very near future.
