In metallic conduit, conductors should be jacketed.

Explanation:
Metallic conduit is a conductive raceway, so the current-carrying conductors inside must have insulation to prevent energizing the metal walls and to protect them from damage. Jacketed (insulated) conductors provide a protective layer that resists abrasion during pulling and installation, stops arcing or shorting to the conduit, and meets the required safety and rating standards for operation in a metal raceway. Bare conductors inside conduit could nick insulation, cause faults, or present shock/arcing hazards, so insulation is required. Hence conductors should be jacketed.
