This question isn't marking right, but the Business Auto Physical Damage coverage covers comprehensive or Specified Causes of Loss and Collision. It also covers transportation expenses. It does not cover garages, truckers, and motor carriers.
A, B, and C are correct. The Physical Damage portion of the Business Auto coverage form contains three principal coverages: Comprehensive, Specified Causes of Loss (a more limited type of Comprehensive coverage), and Collision. Transportation expenses are covered as part of Physical Damage coverage. Garagekeepers insurance is not included in the Business Auto coverage form.
