The Heart starts to develop 17 days after fertilization.
Around 17 days after fertilization, the three primary germ layers—ectoderm, mesoderm, and endoderm—begin to develop, giving rise to various tissues and organs in the body. These layers are essential for the formation of different cell types during embryonic development.
About 17 days after fertilization, embryonic stem cells begin to develop into more specialized cells. At this stage, the embryo forms a structure called the gastrula, which leads to the differentiation of three germ layers: ectoderm, mesoderm, and endoderm. These germ layers give rise to various cell types and tissues in the developing organism.

Around 17 days after fertilization, the embryonic development stage includes the formation of the primitive streak, which marks the beginning of gastrulation. During this process, the cells that will give rise to the three primary germ layers—ectoderm, mesoderm, and endoderm—begin to differentiate. These germ layers are essential for the development of various tissues and organs in the embryo.
At four days after fertilization, the zygote undergoes multiple cell divisions through a process called cleavage. The zygote begins to form a solid ball of cells known as a morula. During this stage, the cells are still undifferentiated and totipotent, meaning they have the potential to develop into any type of cell in the body.

After fertilization, the fertilized egg, now called a zygote, undergoes several cell divisions to form a blastocyst. The blastocyst then implants into the wall of the uterus, where it begins to develop further. This process usually occurs around 6-10 days after fertilization.
About 17 days after fertilization.
the embryo attaches the mother
sperm takes 2-5 days to reach and fertilize the egg and and embryo is produced after a further 8-12 days.
Implantation typically occurs 6-12 days after fertilization. Once the embryo implants in the uterus, it can then develop and grow into a fetus.

A few days after fertilization, the blastocyst forms as the fertilized egg undergoes several cell divisions and begins to develop. This structure will eventually implant into the uterine wall. At this stage, cells have not yet started differentiating significantly, and the development of the eyes occurs much later in the embryonic process. Therefore, the correct answer is B. The blastocyst forms.
At four days after fertilization, the zygote undergoes multiple cell divisions through a process called cleavage. The zygote begins to form a solid ball of cells known as a morula. During this stage, the cells are still undifferentiated and totipotent, meaning they have the potential to develop into any type of cell in the body.
