The spectrophotometric response for the titration of a mixture of $\mathrm{Fe}^{3+}$ and $\mathrm{Cu}^{2+}$ ions against EDTA is given below.The correct statment is:
(a)Volume $\mathrm{ab}=\left[\mathrm{Fe}^{3+}\right]$ and volume $\mathrm{cd}=\left[\mathrm{Cu}^{2+}\right]$
(b)Volume $\mathrm{ab}=\left[\mathrm{Cu}^{2+}\right]$ and volume $\mathrm{cd}=\left[\mathrm{Fe}^{3+}\right]$
(c)Volume $\mathrm{ab}=\left[\mathrm{Fe}^{3+}\right]$ and volume $\mathrm{ab}=$ excess EDTA
(d)Volume $\mathrm{ab}=\left[\mathrm{Cu}^{2+}\right]$ and volume $\mathrm{cd}=$ excess EDTA
