Using 3.1 fb{sup -1} of data accumulated at the {Upsilon}(4S) by the CLEO-II detector, corresponding to 3.3 million B{bar B} pairs, they have searched for the color-suppressed B hadronic decay processes: {bar B}{sup 0} {yields} D{sup 0}(D*{sup 0})X{sup 0}, where X{sup 0} is a light neutral meson {pi}{sup 0}, {rho}{sup 0}, {eta}, {eta}{prime} or {omega}. The D*{sup 0} mesons are reconstructed in D*{sup 0} {yields} D{sup 0}{pi}{sup 0} and the D{sup 0} mesons in D{sup 0} {yields} K{sup -}{pi}{sup +}, K{sup -}{pi}{sup +}{pi}{sup 0} and K{sup -}{pi}{sup +}{pi}{sup +}{pi}{sup -} decay modes. No obvious signal is observed. The authors set 90% C.L. upper limits on these modes, varying from 1.2 x 10{sup -4} for {bar B}{sup 0} {yields} D{sup 0}{pi}{sup 0} to 1.9 x 10{sup -3} for {bar B}{sup 0} {yields} {bar B}{sup 0} {yields} D*{sup 0}{eta}{prime}.
