The South Pacific Nuclear Free Zone Treaty, also known as the Treaty of Rarotonga, was signed on 6 August 1985 by South Pacific nations including Australia, New Zealand, Fiji, and others. The treaty established a nuclear-weapon-free zone in the South Pacific. While the treaty itself was signed by Pacific island nations and Australia and New Zealand, the nuclear powers such as the United States, United Kingdom, and France did not sign the treaty itself but signed its protocols later. France and the United Kingdom signed and ratified the protocols in 1996, and the United States signed but did not ratify them. Therefore, the original question's phrasing is misleading as the treaty was not signed by the US and UK, but France is the correct answer among the options as it is a nuclear power involved in the treaty's protocols related to the zone.

The scientific study of spiders is called arachnology. Arachnology specifically focuses on spiders and related animals such as scorpions, ticks, and mites.
