Which option identifies the two battery types described?

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

Answer: (A)

Batteries are often grouped by the state of their electrolyte: wet cells use a liquid electrolyte that can flow between plates, while dry cells use a paste-like or solid electrolyte and are sealed to prevent spills. Wet cells are common in larger, rechargeable systems (like lead‑acid batteries), whereas dry cells are compact and portable.

The option that mentions both wet cell and dry cell batteries is the best match because it names the two broad categories described, capturing the pair of types being identified. The other choices point to a single type or a single category, which doesn’t reflect the two kinds described together.
