Salt and water is formed as product, when Arrhenius acid and Arrhenius base reacts and the reaction is known as neutralization reaction.
<h3>What is Arrhenius acid-base reaction?</h3>
The concept of acid and base based on the theory of ionization which was first proposed in 1884 by Svante Arrhenius
According to Arrhenius, on dissociation in water the hydrogen-containing compounds which give H+ ions or protons are the acids and the hydroxide compounds which give OH− ions on dissociation in water are bases.
This theory is applicable only to compounds which are dissolved in aqueous solution.
I would say CuSO4 or Copper Sulfate, as option 1 is Methane and would create a fire so heat, and the last one is Sugar which doesn't conduct electricity. And C6H6 I believe is not soluble in water.<span />
