$$\Delta_o$$ increases in the order of $$[CrCl_6]^{3-} < [Cr(CN)_6]^{3-} < [Cr(C_2O_4)_3]^{3-}$$.

ABoth Assertion and Reason are correct and Reason is the correct explanation for Assertion
BBoth Assertion and Reason are correct but Reason is not the correct explanation for Assertion
CAssertion is correct but Reason is incorrect
DAssertion is incorrect but Reason is correct
Correct Answer

Solution

According to spectrochemical series, $$CN^-$$ is a strong field ligand, so it has more $$\Delta_0$$ value.

So, correct order of $$\Delta_0$$ for these complex ions is:

$$[CrCl_6]^{3-} < [Cr(C_2O_4)_3]^{3-} < [Cr(CN)_6]^{3-}$$.
