解析

Labor Code §1725.5 requires a contractor or subcontractor to register with the DIR, and pay the annual fee, before it may bid on, be listed on a bid for, or perform public work subject to prevailing wage. The CSLB issues the licence but runs no public works registration or certification, so that option names an agency that has no such programme. A bond of twice the contract amount is not a bidding prerequisite; bonding comes from the call for bids and Civil Code §9550. The Division of Apprenticeship Standards approves apprenticeship programmes, not contractors.
