A) Phalanges demonstrate equal concavity.
B) Phalanges demonstrate more concavity on one side than on the other.
C) Phalanges demonstrate concavity on one side and convexity on the other.

The projection for the lateral finger demonstrates concavity on one side (the side facing the IR) and convexity on the other (the side facing away from the IR). This is because the finger is curved in a way that the side facing the IR is compressed while the other side bulges outward. Choice A is incorrect because phalanges do not necessarily demonstrate equal concavity. Choice B is incorrect because it implies that there is a difference in concavity between the proximal and distal phalanges, which is not necessarily true.
