I would say that in the diagram attached inside, if electrons flow from the right half-cell to the left one through the wire, the statement that is true should be the first one - A) the metal strip on the right has a lower activity than the one on the left. However, I am not entirely sure about this one.
The correct answer is A. The metal strip on the right has a lower activity than the one on the left.
Metal is known as the material which is typically hard when in a solid state, it has good electrical and thermal conductivity, shiny and opaque. Metals are malleable to mean they can be oppressed or hammered permanently out of shape even without cracking or breaking. Metals can also be used to refer to all elements in the star that are heavier and lighter than helium and hydrogen.
