Somites are evidence of (a) a structure from ectoderm, (b) a structure from endoderm, (c) a structure from lateral plate mesoderm, (d) segmentation in the human body.

Developmental biology suggests that embryonic development is known as embryogenesis. The fertilized zygote undergoes cell division and differentiation to produce a fully formed body. This process has some stages that are formed which can persist or even deplete or change their form.

The somites- a set of blocks that are bilaterally paired. It originates from the paraxial mesoderm and formed in segmented animals along the head-to-tail axis during the somitogenesis stage of embryogenesis. The somites of vertebrates have subdivisions like myotomes, sclerotomes, syndetomes, and dermatomes. It gives rise to the vertebral column, rib cage, bones, skeletal muscles, tendons, cartilage, and skin.

Thus, option "c" is the correct answer. All the other options are wrong because somites do not originate from the endoderm or ectoderm nor they are involved in segmentation.
