A Both are paramagnetic with three unpaired electrons
B Δ0 value of A is less than that of B
C Î0 values of A and B are calculated from the energies violet and yellow light, respectively.
D Both absorb energies corresponding to their complementary colors.

The correct answer is:
Δ0 values of A and B are calculated from the energies violet and yellow light, respectively.

Solution:
Δ 0 A < Δ 0 B, both complexes have CN=6, B has strong field ligand and A has weak field ligand
so Δ 0 A < Δ 0 B
In both complexes, Cr has 3 unpaired electrons and hence, will be paramagnetic CrH2OCl3
