B. momentum
C. energy
D. current

Explanation

### Step-by-Step Solution:

1. **Understanding Lenz's Law**: Lenz's Law states that the direction of induced current in a closed loop is such that it opposes the change in magnetic flux that produced it. This means that if the magnetic flux through a loop increases, the induced current will flow in a direction that creates a magnetic field opposing the increase.

2. **Magnetic Flux and Energy**: When there is an increase in magnetic flux through a loop, it implies that the magnetic field strength is increasing. This increase in magnetic flux is associated with an increase in magnetic energy within the loop.

3. **Conservation of Energy**: According to the law of conservation of energy, energy cannot be created or destroyed; it can only be transformed from one form to another. In the context of Lenz's Law, this means that the energy associated with the magnetic field must remain constant.

4. **Induced EMF and Current**: To maintain energy conservation when the magnetic flux increases, the loop induces an electromotive force (EMF). This induced EMF generates a current in the loop that flows in a direction to oppose the change in magnetic flux.

5. **Direction of Induced Current**: If the magnetic field is increasing in a certain direction, the induced current will flow in a direction that creates a magnetic field opposing the increase. For example, if the magnetic field is increasing outwards from the loop, the induced current will flow in a clockwise direction to create a magnetic field that opposes this increase.

6. **Conclusion**: Therefore, Lenz's Law is fundamentally a consequence of the law of conservation of energy. It ensures that the energy within the system remains constant by opposing changes in magnetic flux.

### Final Answer:
Lenz's law is a consequence of the law of conservation of energy.
