Assertion (A) : ${\left[\mathrm{Ti}{\left({\mathrm{H}}_2\mathrm{O}\right)}^{3+}\right]}^{3+}$is coloured while ${\left[\mathrm{Sc}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]}^{3+}$is coloured less 
Reason (R) : d-d transition is not possible in${\left[\mathrm{Sc}{\left({\mathrm{H}}_2\mathrm{O}\right)}_6\right]}^{3+}$

Both Assertion and Reason are correct and the reason is the correct explanation of the Assertion.  

Both Assertion and Reason are correct but Reason is not correct explanation of the Assertion.
