The correct answer is C. Common flashlight batteries are primary dry-cell batteries.
A secondary battery is a type of battery that can be recharged by passing an electric current through it in the opposite direction of the discharge current. This process is called charging. Secondary batteries are also known as rechargeable batteries.
A primary battery is a type of battery that cannot be recharged. Once the battery is discharged, it must be replaced. Primary batteries are also known as non-rechargeable batteries.
A wet-cell battery is a type of battery that uses a liquid electrolyte. The electrolyte is a substance that conducts electricity. Wet-cell batteries are typically used in cars and other vehicles.
A dry-cell battery is a type of battery that uses a solid electrolyte. The electrolyte is a substance that conducts electricity, but it is not a liquid. Dry-cell batteries are typically used in flashlights, toys, and other small devices.
In conclusion, common flashlight batteries are primary dry-cell batteries.
