Answer: (C) The production of tissue-specific proteins.
Explanation:
The cell differentiation is the process in which the cell change from one cell place to another place. It basically occur due to the process of gene expression.
The cell differentiation involve the production of the specific tissue protein known as muscle actin. In cell differentiation, the pluripotent stem cell basically go in the specific differentiation level and then reach in the state of fully differentiation.
The fully differentiation produced a specific function that the production of the protein. Therefore, option (C) is correct.

gamete: a mature haploid male or female germ cell which is able to unite with another of the opposite sex in sexual reproduction to form a zygote.

algae: a simple, nonflowering, and typically aquatic plants of a large group that includes the seaweeds and many single-celled forms. algae contains chlorophyll but lack true stems, roots, leaves, and vascular tissue.
fungi:any group of spore-producing organisms feeding on organic matter, including molds, yeast, mushrooms, and toadstools.
lichen:a simple slow-growing plant that typically forms a low-crusty,leaflike, or branching growth on rocks, walls, and trees.
