  Flux-integrated semi-exclusive differential and integral cross sections for
quasi-elastic neutrino charged-current scattering on argon are analyzed. We
calculate these cross sections using the relativistic distorted-wave impulse
approximation and compare with recent MicroBooNE data. We found that the
measured cross sections can be described well within the experimental
uncertainties with value of the nucleon axial mass $1 < M_A < 1.2$ GeV. The
contribution of the exclusive channel $\boldmath{(\nu_{\mu}, \mu p)}$ to the
flux-integrated inclusive cross sections is about 50\%.
