D Correct answer
Explanation

V2+ has d3 electronic configuration and it is empowered in a weak field ligand. The term symbol is calculated by the formula- 2s+1 LJ For d3, n = 3 s = n/2 = 3/2 2s + 1 = 4 L = 3 = F J = (L + s) to (L - s) = 2, 1, 0 term symbols = 2s + 1 LJ = 4F9/2, 4F7/2, 4F5/2, 4F3/2 The ground state term for V2+ is 4F3/2.
