Final answer:
The bone that is not in the foot is the metacarpal bone, which forms the palm of the hand. The foot consists of the metatarsal bones, phalanges, and the lateral cuneiform bone (option a).
Step-by-step explanation:
The bone that is not in the foot is a. Metacarpal Bones. The bones that make up the foot include b. Metatarsal Bones, c. Phalanges, and d. Lateral Cuneiform Bone.
The metacarpal bones form the palm of the hand and have nothing to do with the foot. The five metatarsal bones are located between the tarsal bones of the posterior foot and the phalanges of the toes, forming the anterior half of the foot. The toes contain a total of 14 phalanx bones (phalanges), which include the proximal, middle (except in the big toe), and distal phalanges. The lateral cuneiform is one of the tarsal bones of the foot that articulates with metatarsals and helps form the arch of the foot.
Hence, the answer is option a.
