The adjustment that would most likely result in a reduction of a solenoid's magnetic field strength is:
**Lowering the current while reducing the number of coils.**
This is because the magnetic field strength of a solenoid is directly proportional to both the current flowing through the coils and the number of coils. Reducing either of these factors (or both) will lead to a decrease in the magnetic field strength.
