Totipotent stem cells are primarily found in the early stages of embryonic development, specifically in the zygote and the first few cell divisions that follow. At this stage, each cell has the potential to develop into any cell type in the organism, including both embryonic and extra-embryonic tissues. As development progresses, cells become pluripotent or multipotent, losing their totipotent capabilities. Therefore, the most totipotent stem cells are present in the fertilized egg and the first few blastomeres of the embryo.
Totipotent stem cells are present in the earliest stages of embryonic development, specifically in the fertilized egg (zygote) and the first few divisions of the embryo. Therefore, the zygote contains the greatest number of totipotent stem cells. As development progresses, these cells differentiate into pluripotent and multipotent cells, losing their totipotency.

Among the options typically provided, the zygote contains the greatest number of totipotent stem cells, as it has the potential to develop into any cell type in the body, including extraembryonic tissues. As development progresses, cells become more specialized and lose their totipotency.
Unipiot is the right one trust me
Totipotent
stem cells are undifferentiated cells which could be totipotent as well as pluripotent.
5-7 days embryonic cells are totipotent 6 week embryo cells are pluripotent
