How can two cells of a complex multicellular organism have t

How can two cells of a complex multicellular organism have the same genome, but markedly different structures and functions?

Question 1 options:

During differentiation, as cells become specialized, they lose portions of their genome that are no longer needed.

Once differentiation begins, the genome no longer controls cellular functions.

Part of the process of differentiation of cells is to create mutations in the genome.

Different genes are expressed in different cells.
