D Devendra Khairwa

In ground state,Ti has 23 electrons with electronic configuration 3d34s2.

The oxidation state of Ti in the given compound is +3.

Hence it will now have the configuration 3d2. Since it has 2 unpaired electrons and has the ability to undergo d-d transition, the given complex gives violet colour.
