Which band houses part of the right bundle branch?

Explanation:
The moderator band (septomarginal trabecula) in the right ventricle houses part of the right bundle branch. This muscular band runs from the interventricular septum to the base of the anterior papillary muscle and carries a portion of the conducting pathway that continues into the right ventricle to coordinate its contraction. Other structures listed are not involved in housing conduction fibers: the crista terminalis is a ridge in the right atrium, Bachmann's bundle connects the atria, and the chordae tendineae anchor valve leaflets.
