Answer:
electronic configuration of chromium is [AR]3d5 4s1
after vanadium the electronic configuration of chromium must be [AR] 3d4 4s2
but half filled or fully filled orbitals are more stable than ground electronic configuration
so 4s2 electron jump into 3d orbital so it's configuration would be
[AR] 3d5 4s1
option (C)
hope it helps ...
