Solution

The correct option is D Large amount of hydration enthalpy
Lithium ion is small in size on account of which more solvent molecules can easily surround around the cationic sphere. so, large amount of hydration energy is released and on account of Large amount of hydration energy makes it strongest reducing agent inspite of its highest ionisation enthalpy.
