The first step in the two-step process of making a solution is the breakdown of the solute source into Atomic particles
for a solution to break the solute must be dissociated and break into the atomic particles
so correct option is D
hope it helps
Transition metals seem to have fairly even levels of reactivity though it seems they to react more with bases than acids. If I didn’t know from the lessons, I would say alkali and alkaline earth metals weren’t very reactive.
(That's my answer when I did a lab about the reaction of metals for chemistry at least.)
