	C.	It post-mitotic.
	D.	A and B

Answer 1

B and C

Differentiated cells are those which contains specific proteins and perform specific functions.

First option is incorrect because totipotent cells are undifferentiated cells and give rise to different types of cells when stimulated with specific proteins and growth factors.

Second option is correct because differentiated cells show transcription and translation of specific gene which leads to the presence of specific proteins in these cells.

Third option is correct because the cell formed after mitosis is differentiated and can perform all the functions of the tissue in which it is present.
