Answer
Correct option: B.
$3.87\ B.M.$
The magnetic moment is associated with its spin angular momentum and orbital angular momentum.
Spin only magnetic moment value of $Cr^{3+}.$ ion is $3d^{3+}$
Hence, magnatic moment
$(\mu)=\sqrt{\text{n(n+2)}}\text{ BM}$
$=\sqrt{3(3+2)}=\sqrt{15}$
$=3.87\text{ BM}$
Spin only magnetic moment value of $Cr^{3+}.$ ion is $3d^{3+}$
Hence, magnatic moment
$(\mu)=\sqrt{\text{n(n+2)}}\text{ BM}$
$=\sqrt{3(3+2)}=\sqrt{15}$
$=3.87\text{ BM}$
