The correct answer is the option 3 - Heart.
Mesoderm is the middle layer of the 3 germ layers of the developmental animal embryo. It lies in between the ectoderm and the endoderm.
In vertebrates, the mesoderm gives rise to the connective tissues like the muscles, blood, blood vessels, bone marrow, lymphatic vessels, lymphoid tissues, and other organs like the kidneys, body cavities, gonads, heart, ureters, genital ducts, etc.
The lateral plate of the mesodermal layer gives rise to the heart, to the blood cells and the blood vessels of the circulatory system.
