Correct option is B)
Value of magnetic moment depends upon number of unpaired electrons. All given metal ions (except Ti3+(3d1)) have either fully filled d-subshell ( Zn2+,Cu+) or empty d-subshell ( Sc3+). As such only Ti3+ has a net value of magnetic moment.
Magnetic moment of Ti3+=n(n+2)BM=1(1+2)BM=3BM=1.73BM.
