Solution
The correct option is C Sodium
Second messengers are the organic molecules and sometimes the metal ions, acting as intracellular signals, whose production or release usually amplifies a signal such as a hormone, received at the cell surface. Sodium (Na) is not a second messenger to be discovered. In addition to cyclic AMR Cyclic Guanosine Monophosphate (CGMP) functions as a second messenger in certain cases. Calcium ions (Ca++) also act as second messenger in phospholipase c - ca* second messenger system.
So, the correct answer is 'Sodium'.
