Solution

The correct option is B $K^{+}, Z n^{2 +}, C d, S n^{2 +}$
Paramagnetic and diamagnetic properties depend upon the electronic configuration. If the element contains unpaired electrons in the electronic configuration then, it will be paramagnetic otherwise it will be diamagnetic.

Here, $K^{+}, Z n^{2 +}, C d, S n^{2 +}$ are diamagentic and $C r^{3 +}, C o^{3 +}$ are paramagnetic.
