(C) The magnetic moment $(\mu)$ is calculated using the formula $\mu = \sqrt{n(n+2)} 	ext{ B.M.}$,where $n$ is the number of unpaired electrons.For $3d^1$,$n = 1$,$\mu = \sqrt{1(3)} = 1.73 	ext{ B.M.}$For $3d^8$,$n = 2$,$\mu = \sqrt{2(4)} = 2.83 	ext{ B.M.}$For $3d^5$,$n = 5$,$\mu = \sqrt{5(7)} = 5.92 	ext{ B.M.}$For $3d^7$,$n = 3$,$\mu = \sqrt{3(5)} = 3.87 	ext{ B.M.}$Thus,the $3d^5$ configuration has the highest number of unpaired electrons $(n=5)$,resulting in the highest magnetic moment.

Atom/Ion	Electronic Configuration
$(1) \ Cu$	$(A) 1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 3d^{10}$
$(2) \ Cu^{2+}$	$(B) 1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 3d^{10}, 4s^2$
$(3) \ Zn^{2+}$	$(C) 1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 3d^{10}, 4s^1$
$(4) \ Cr^{3+}$	$(D) 1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 3d^9$
	$(E) 1s^2, 2s^2, 2p^6, 3s^2, 3p^6, 3d^3$
