According to the second law of thermodynamics, in any energy transfer or transformation, the total entropy of a closed system always :
Increases
Increases option is correct.
The second law of thermodynamics states that the entropy of an isolated (closed and adiabatic) system never decreases during a spontaneous process; it either increases or, for a reversible process, stays constant. In practice all real energy transfers and transformations are irreversible, so entropy strictly increases — captured by Clausius's inequality \(dS \ge \dfrac{\delta Q}{T}\).
This principle explains why heat flows spontaneously from hot to cold, why perpetual-motion machines of the second kind are impossible, and why every real energy conversion carries an efficiency penalty.
Entropy cannot decrease overall, cannot “reach zero” in a real closed system (that would violate the third law framing as well), and entropy is a positive-definite quantity so “negative” is not physically meaningful.
