Which option is NOT one of the two battery types described?

• A. Wet cell batteries
• B. Dry cell batteries
• C. Lead-acid batteries
• D. Nickel-cadmium batteries

Answer: (D)

Two broad battery categories are wet cell and dry cell. Wet cells use a liquid electrolyte, while dry cells use a paste electrolyte. Lead-acid is a common example of a wet-cell chemistry, so it fits within the described wet/dry grouping. Nickel-cadmium, however, is a distinct chemistry (NiCd) that isn’t categorized as a wet or dry cell in that description, so it isn’t one of the two types described.
