Who did Captain Cook name the Sandwich Islands after?

Captain Cook named the Sandwich Islands after his sponsor, the Earl of Sandwich. This naming was a tribute to John Montagu, the 4th Earl of Sandwich, who was instrumental in financing Cook's voyages. The Earl was a significant figure in British history, and his influence in maritime exploration during that era was considerable. Naming the islands after him reflects the practice of explorers during that time to honor their patrons or benefactors. The other options do not pertain directly to the historical context of Cook's voyages or the nature of his sponsorship, making them less relevant in this case.
