C. elegans embryo uses both autonomous and conditional modes of specification. Conditional specification at the 4-cell stage can be seen in the development of the endoderm cell lineage and also in the establishment of dorsal-ventral axis. Following are few statements regarding this figure:

A. If the P2 cell is removed at the early 4-cell stage, the EMS cell will divide into two MS cells and endoderm will be made.

B. In pop-1 deficient embryos, both EMS daughter cells become MS cells.

C. When the position of ABa and ABp was reversed, their fates get reversed and no normal embryo forms.
