Best answer
Correct choice is (b) Standard hydrogen electrode

The best explanation: SHE means a Standard hydrogen electrode. It is used to calculate the potential of other elements by arbitrarily defined as zero. The standard conditions of SHE is 1 atm pressure of H2 gas, 25°C temperature and non-corroding conditions for pure metals.
