The right answer is D.

Tolerance occurs when a person consumes a substance for a prolonged period. The body becomes accustomed to its effects. This results in the need for higher and higher doses to feel the same pleasant effects as the first few times.

Explanation:

The function of protein kinase is to transfer a phosphate group to the amino-acid present in a protein and the function of protein phosphatase is to catalyze the removal of the attached phosphate group from amino acid of a protein.

Protein dephosphorylation is an important event in the post-translational modification process. Through dephosphorylation, phosphatases change the protein behavior by activating and deactivating the proteins.

Phosphorylation and dephosphorylation of proteins are important in managing several crucial processes in the cell like cell signaling, apoptosis, cell cycle, etc. So the right answer is C.
