Answer
This statement is incorrect for secondary cells, as they do not have a continuous supply of reactants; instead, they rely on the reversible chemical reactions within the battery.
Step 2

Answer
This statement is misleading. While many battery types can operate over a range of temperatures, this flexibility does not strictly define a secondary cell.
Step 3
C. the polarity of the electrodes remains unchanged.

Answer
This statement is false. In a secondary cell, during the discharging process, the polarity of the electrodes changes.
Step 4
D. it can operate as both a galvanic and electrolytic cell.

Answer
This statement is correct. Secondary cells can function as galvanic cells (when discharging) and electrolytic cells (when charging), which defines their versatility.
