We study the indication of different large branching ratios between B^\ensuremath-\ensuremath→D(*)0K^\ensuremath-K0 and Bd\ensuremath→D(*)+K^\ensuremath-K0 observed by Belle. Interestingly, the same situation is not found in the decays \stackrel\ensuremath→BD(*)K^\ensuremath-K*0. If no intermediate resonances exists in the decays B^\ensuremath-\ensuremath→D(*)0K^\ensuremath-K0, a puzzle will arise. We find that the color-suppressed processes B^\ensuremath-\ensuremath→D(*)0a0^\ensuremath-(1450) with a0^\ensuremath-(1450)\ensuremath→K^\ensuremath-K0 could be one of the candidates to enhance the BRs of B^\ensuremath-\ensuremath→D(*)0K^\ensuremath-K0. Our conjecture can be examined by the Dalitz plot technique and the analysis of the angular dependence of the K^\ensuremath-K0 state at B factories.
