Solution

The correct option is A
Energy is liberated

As you know that surface area is more in case of drops as compared to a merged bigger drop,which implies that surface energy is larger in case of drops and comparatively lower in case of a merged bigger drop.
$\Rightarrow V_{1} - V_{f} \to p o s t i t i v e o r V_{i} > V_{f}$
Which implies energy is liberated in this process
