We propose that the search of the B→D*sJM decays, M = D, π, and K, can discriminate the different theoretical postulations for the nature of the recently observed D*sJ mesons. The ratio of the branching ratios B(B→D*sJM)/B(B→D(*) sM)≈1 (0.1) supports that the D*sJ mesons are quark-antiquark (multiquark) bound states. The Belle measurement of the B→D*sJD branching ratios seems to indicate an unconventional picture.
