Final answer:
The tarsal bone known as the heel bone is the calcaneus, which is the largest tarsal bone in the foot, forming the heel and supporting weight transfer.
Step-by-step explanation:
The tarsal bone commonly referred to as the "heel bone" is b. Calcaneus. The calcaneus is the largest of the tarsal bones and forms the prominence at the back of the foot, or the heel. It serves as the main point of weight transfer from the tibia to the ground, and it supports the talus bone above. This bone articulates inferiorly with the talus and anteriorly with the cuboid bone, providing structural integrity to the foot.
