The wrist is made up of eight tiny bones (carpal bones) and two large bones in the forearm — the radius and ulna. Each finger has one hand bone (metacarpal) and three finger bones (phalanges), but each thumb has one metacarpal bone and two phalanges.
The carpals are eight bones present in the wrist of the hand. It helps in moving the wrist, and it also attaches the hand to the wrist.
Therefore, the correct option is d, carpals.

Answer:
The P waves undergoes compression and dilation during motion in its direction of propagation. This waves reaches the station first because the P waves travels at a speed, that is much faster in comparison to the S waves. The S waves are the secondary waves and are commonly known as the shear waves.
The P waves have the ability to travel in both solid as well as in liquid, whereas the S waves can propagate only in solid region because they are absorbed at the core-mantle boundary.
Thus, the P waves will arrive the station first and the difference between the arrival of P and S waves are plotted in the graph that helps in depicting the epicenter and the amount of energy released during an earthquake.
