The correct answer is Sweden.

The Nobel Prize is a set of annual international awards bestowed for academic, cultural, and/or scientific advances. The will of the Swedish inventor, industrialist, and armaments manufacturer Alfred Nobel established the Nobel Prizes in 1895, five years before his death. Nobel was influenced by the 1894 dynamite factory accident in which more than 50 people were killed, including five of his employees. His will stipulated that most of his fortune be used to create a series of prizes “to those who, during the preceding year, shall have conferred the greatest benefit to humankind.”

The Nobel Prizes are awarded by Swedish and Norwegian institutions in accordance with the will of Alfred Nobel. The Nobel Prize in Chemistry, Physics, Physiology or Medicine, Literature, and Peace are awarded by the Royal Swedish Academy of Sciences, the Royal Swedish Academy of Engineering Sciences, Karolinska Institutet, and the Norwegian Nobel Committee, respectively. The Nobel Memorial Prize in Economic Sciences was established in 1968 by the Sveriges Riksbank, Sweden’s central bank, and is administered by the Royal Swedish Academy of Sciences.

The Nobel Prizes are widely regarded as the most prestigious awards available in their respective fields. The prizes are presented in Stockholm at an annual ceremony on December 10, the anniversary of Nobel’s death.
