Can an unlicensed auctioneer call bids at any time for any reason?

An unlicensed auctioneer can call bids only if they are supervised by a licensed auctioneer. This is based on the regulations governing auctioneering practices, which are designed to protect the public and ensure that auctions are conducted fairly and legally. Supervision by a licensed auctioneer ensures that the unlicensed individual is guided by someone who understands the legal and ethical standards of the auction profession.

The other options suggest scenarios in which unlicensed auctioneers could operate independently or in inappropriate settings, which goes against the legal requirements. Therefore, the correct understanding is that unlicensed auctioneering is permissible only under the close oversight of a licensed professional.
