If the Reaction Is Taking Place in a Basic Solution $\rightarrow$

If the reaction is taking place in a basic solution, the balanced equation is:

A) 14H₂O + 2Cr₂O₇²⁻ + 2Fe $\rightarrow$ 2Cr³⁺ + 14OH⁻ + 4Fe³⁺.
B) 14H₂O + Cr₂O₇²⁻ + 5Fe $\rightarrow$ 2Cr³⁺ + 14OH⁻ + 5Fe³⁺.
C) 7H₂O + Cr₂O₇²⁻ + 2Fe $\rightarrow$ 2Cr³⁺ + 14OH⁻ + 2Fe³⁺.
D) H₂O + Cr₂O₇²⁻ + Fe $\rightarrow$ Cr³⁺ + OH⁻ + Fe³⁺.
E) 7H₂O + 7Cr₂O₇²⁻ + 7Fe $\rightarrow$ 7Cr³⁺ + 14OH⁻ + 7Fe³⁺.
