We report measurements of the decays {ital D}{sup +}{r arrow}{ital {bar K}}{sup 0}{pi}{sup +}, {ital D}{sup +}{r arrow}{ital {bar K}}{sup 0}{ital K}{sup +}, and {ital D}{sub {ital s}}{sup +}{r arrow}{ital {bar K}}{sup 0}{ital K}{sup +} from Fermilab photoproduction experiment E691. The relative branching fractions obtained are {ital B}({ital D}{sup +}{r arrow}{ital {bar K}}{sup 0}{pi}{sup +})/{ital B}({ital D}{sup +}{r arrow}{ital K}{sup {minus}}{pi}{sup +}{pi}{sup +})=0.274{plus minus}0.030{plus minus}0.031, {ital B}({ital D}{sup +}{r arrow}{ital {bar K}}{sup 0}{ital K}{sup +})/{ital B}({ital D}{sup +}{r arrow}{ital {bar K}}{sup 0}{pi}{sup +})=0.271{plus minus}0.065{plus minus}0.039, and {ital B}({ital D}{sub {ital s}}{sup +}{r arrow}{ital {bar K}}{sup 0}{ital K}{sup +})/{ital B}({ital D}{sub {ital s}}{sup +}{r arrow}{phi}{pi}{sup +})=1.15{plus minus}0.31{plus minus}0.19.
