Verified step by step guidance

1. Understand the three primary germ layers formed during embryonic development: ectoderm, mesoderm, and endoderm.
2. Recognize that the ectoderm is the outermost layer and is responsible for forming structures such as the skin, nervous system, and sensory organs.
3. Identify the organs listed in the problem: kidneys, heart, liver, and skin, and determine which of these are derived from the ectoderm.
4. Recall that the skin is a major organ that develops from the ectoderm, while the kidneys, heart, and liver develop from the mesoderm and endoderm.
5. Conclude that the correct answer is skin, as it is the body part that develops from the ectoderm during human development.
