Which statement is true about the cells in multicell organisms?

Well what's the statement

A) The cells contain different genes and therefore express different genes.

Explanation:

In multicellular organisms, cells contain different genes and therefore express different genes.

If all the differentiated cells in an organism contain the same genes, and all the genes have the potential to be expressed, how do the cells become differentiated or specialized? The answer to this question is in the genes that are active in different cell types, that is, the great differences between cells in an organism result from the selective expression of genes. As a developing embryo undergoes successive divisions, specific genes are activated in different cells for different periods of time. Groups of cells follow distinct developmental pathways, and each group develops a particular type of tissue. Finally, in the mature organism, each cell type has a different pattern of genes that are expressed
