I think the correct answer would be B. The process of electroplating uses a direct current in order to give a cheap metal the apperance and resistance of a more expensive metal by coating it with a certain metal. The current reduces the dissolved metal ions to form a thin coating on a surface.
Answer: Arsenic
Explanation:. Arsenic, is found in several different chemical forms in paving roads--- arsenic release from asphalt, rocket fuel--- from combustion of fuel causing release of arsenic and carbon monoxide and among the composition of rat poison in different oxidation states,which can lead to toxicity called arsenic poisoning--- which occurs when much arsenic is accumulated in the body causing acute and chronic adverse health effects, from diarrhea to cancer.
C₆H₄(COOH)(COOK) + CsOH = C₆H₄(COOCs)(COOK) + H₂O
C₆H₄(COOH)(COO)⁻ + K⁺ + Cs⁺ + OH⁻ = C₆H₄(COO)₂²⁻ + K⁺ + Cs⁺ + H₂O
C₆H₄(COOH)(COO)⁻ + OH⁻ = C₆H₄(COO)₂²⁻ + H₂O

A solution must have both a solute and a solvent, and they must exist in solution together. the solute must be dissolved in the solvent; salt does not dissolve in a sugar bowl, nor does oil dissolve in water; it is a non polar molecule. we know that sugar (the solute) when added to water(solvent) will dissolve, creating a solution.
therefore, B
