Solution

The correct option is D
Mercury Cell

Aisu will select a mercury battery as they are used in the shape of button cells for watches, hearing aids, cameras and calculators. Lithium-ion, Lead-acid and Nickel-cadmium cells are too bulky to be used in a watch and they need to be recharged frequently.
