Marcos Wu · Answer 1

Option C

Explanation:

When a chemical compound inhibits the corresponding protein tyrosine phosphatase from adding a phosphate group to the proteins (known as phosphorylation) and hence leads to its inactivation. This causes large cell division at a fast rate. This phenomenon is used in treating cancer as an anti-cancer treatment methodology where harmful cancer cell growth is prohibited and normal cell division occurs at a fast pace

Hence, option C is correct
