Explanation:
To do this by hand, you need to understand the rules of scientific notation.
The correct answer is compound.
The compounds comprise two or more elements, which are bonded together chemically, and can be dissociated, that is, distinguished by reforming and breaking the chemical bonds, by the decomposition reactions, like thermal decomposition or electrolysis. The process of decomposition generate simpler compounds or individual elements.
The solution with the lowest pH would mean that it is an acid, specifically a strong acid which completely dissociates into ions in aqueous solution. Among the choices listed above, I think the correct answer is option D. It is nitric acid that will have the lowest pH because it is the only strong acid in the group.
