Answer»

Right choice is (c) less than

Easiest explanation: ALTHOUGH the alkaline earth METALS are reductants in nature, their reducing POTENTIAL is not as greater as alkali metals. Beryllium has a negative value when compared to the other elements in its group, this is due to the LARGE hydration energy associated with the small size of beryllium.
