AIt cannot be discharged
BIt holds no electrolyte
CIt cannot be recharged
DIt has only one electrode
Answer & Solution
Correct answer: C. It cannot be recharged
1. A secondary battery can be driven backwards by an external supply and used again.
2. A primary battery cannot, so it is a single use battery.
3. The zinc carbon dry cell is a familiar primary battery.
4. A battery that could not discharge would never have supplied current in the first place.
