The correct answer is B. Secondary voltage.
A step-down transformer is a type of transformer that reduces the voltage in an electrical circuit. The primary winding of a step-down transformer has more turns of wire than the secondary winding. This means that the current in the primary winding is less than the current in the secondary winding. The voltage in the secondary winding is inversely proportional to the number of turns of wire in the secondary winding. Therefore, the voltage in the secondary winding is less than the voltage in the primary winding.
Option A is incorrect because the primary voltage is larger than the secondary voltage in a step-up transformer.
Option C is incorrect because both the primary voltage and the secondary voltage are present in a step-down transformer.
Option D is incorrect because it is possible to say which voltage is larger in a step-down transformer.
Option E is incorrect because the answer is not none of the above.
