Heart
The Heart starts to develop 17 days after fertilization.
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.

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.
The blastocyst will implant itself into the uterine wall, where it will develop and grow into an embryo. This process is known as implantation and typically occurs around 6-10 days after fertilization.
The Heart starts to develop 17 days after fertilization.
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.
the embryo attaches the mother
About 17 days after fertilization.
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.
