The correct answer is: D. current drawing will be very high.
When a battery is wrongly connected on charge, the current drawn by the battery will be very high. This is because the battery is trying to force current through the charger in the wrong direction. This can cause the battery to overheat and even explode.
Option A is incorrect because the battery is not delivering current, it is drawing current.
Option B is incorrect because the battery is drawing current, not zero current.
Option C is incorrect because the battery is drawing a high current, not a very small current.
It is important to always connect a battery correctly to a charger to avoid damage to the battery or the charger.
