The information below describes a redox reaction.
what is the final, balanced equation for this reaction?

The answer to your question is the first option

Explanation:

Just remember that to balance using this method,

first look for the elements that change their oxidation number, and

later count the number of electrons that changed,

later identify which element oxidazes and which reduces and

finally cross the number of electrons that change in each semireaction and write these numbers in the main reaction.

               2Cr⁺³ (aq) + 6Cl⁻ (aq) ⇒ 2Cr(s) + 3Cl₂ (g)

                              2                  Cr                 2

                              6                  Cl                  6
