Detailed Solution

Concept: The middle germ layer that covers an animal's embryo is called the mesoderm. This is located between the embryo's ectoderm and endoderm layers. At the time of maturation, this mostly produces the connective specialised tissues.
The heart is the organ responsible for pumping blood to all the different bodily parts. It is derived from the embryo's mesoderm. Mesodermal cells were primarily the source of the muscle and connective tissue. Mesodermal origin is the source of skeletal muscle, cardiac muscle, red blood cells, dentine in the teeth, kidney cells in the kidney, and smooth cells in the gut.
Hence, the correct answer is option 3.
