Lenz's law is a consequence of the law of conservation of

The correct answer is Option (3) → energy

The induced current always opposes the change that produces it. When a magnet is pushed towards a coil, the induced current makes the coil repel the magnet, so work must be done against this force, and that work appears as electrical energy in the circuit. If the induced current aided the change instead, the magnet would accelerate by itself and energy would be created from nothing. So Lenz's law follows from conservation of energy.
