A foremost task in understanding the nature of the $X(3872)$ involves thediscrimination of the two-quark and multiquark configurations. In this work, wepropose a method to probe the short-distance component of the $X(3872)$ bymeasuring the ratio between the $B_c$ semileptonic and nonleptonic decays intothe $X(3872)$. We demonstrate that if the $X(3872)$ production mechanism isthrough the $\bar cc$ component, the ratios would be universal and could bereliably predicted in theory. Measurements of these ratios at LHC and thenext-generation electron-positron colliders are capable ofvalidating/invalidating this production mechanism and providing deeper insightsinto the nature of the $X(3872)$.
