Solution
The correct option is A 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. ⇒V1−Vf→postitiveorVi>Vf
Which implies energy is liberated in this process
