B) Technician B only
C) Both A and B
D) Neither A nor B
Sulfated Battery
A battery condition where lead sulfate crystals form on the battery’s electrodes, usually due to prolonged discharging, reducing its capacity and performance.
Freeze
A physical state transition where a liquid becomes a solid, typically when temperature drops below its freezing point.

Final Answer :
B
Explanation :
Technician B is correct because a sulfated battery, which has lead sulfate crystals built up on its plates, typically shows a false state of charge, leading to an abnormally high voltage reading immediately after charging. Technician A is incorrect because a sulfated battery, due to its reduced ability to hold a charge, is actually more likely to freeze in extreme cold temperatures, not less.
