The aspect I fear most re so called "standardized tests" is that the
writers and administrators may not know physics very well:

In this case I would not say that "current is applied"   Current isn't
"applied;" It is the result of _voltage_ being applied.

But if indeed there is a current, the light bulb _would_ respond.

The question is inept.
