Answer is Wrong!
Answer is Right!
The correct answer is A. increases.
Sulphate crystals form on the lead plates of a lead-acid battery when it is not used or is not used properly. These crystals can build up and cause the internal resistance of the battery to increase. This can make it difficult for the battery to start the car or provide enough power for accessories.
Option B is incorrect because sulphation causes the internal resistance of the battery to increase, not decrease.
Option C is incorrect because sulphation causes the internal resistance of the battery to increase, not remain the same.
Option D is incorrect because sulphation does cause the internal resistance of the battery to increase.
