Select the most appropriate antonym of the given word.

EQUILIBRIUM

imbalance

The correct answer is option 2. imbalance.

"Equilibrium" refers to a state of balance or stability where opposing forces or influences are in a state of relative equality, resulting in a stable overall condition.

On the other hand, "imbalance" is the opposite of equilibrium. It describes a lack of balance or stability, often characterized by unequal distribution or unequal forces acting on a system.

Therefore, in the context of antonyms, "imbalance" is the most appropriate choice as it represents the opposite of "equilibrium," indicating a lack of stability or balance instead of a stable and balanced condition.
