Answer
This option is incorrect. In a lead-acid battery, oxidation occurs at the anode, which is the negative terminal during the discharging process, but when recharging, we focus on reduction.
Step 2
B. positive terminal of the battery where reduction will occur.

Answer
This option is correct. During the recharging process of a lead-acid battery, the positive terminal of the power supply connects to the positive terminal of the battery, promoting reduction, where lead ions gain electrons.
