All the options provided are the names of auction houses.

Option-1 signifies that only Christie`s is an auctioneer, which is true as Christie`s is indeed a famous auction house, but it is not the only one of the three listed.

Option-2 suggests that only Christie`s and Sotheby`s are auctioneers, which is partially true since both Christie`s and Sotheby`s are well-known for their auctioning services, however, it inaccurately excludes Osian`s.

Option-3 suggests that only Osian`s and Sotheby`s are auctioneers which is again partially correct as these two are reputable auction houses, but it unjustly leaves out Christie`s.

Option-4 correctly states that all three, i.e., Christie`s, Osian`s, and Sotheby`s, are significant auction houses dealing in art, jewellery, real estate, and other luxury goods worldwide. Hence, the correct answer is Option-4.
