The chosen answer is correct because Sauternes, a renowned sweet wine from the Bordeaux region of France, is primarily produced from a blend of Semillon, Sauvignon Blanc, and Muscadelle grapes.

Semillon is the main grape variety used in Sauternes, valued for its ability to develop noble rot, or Botrytis cinerea, which is essential for producing the rich sweetness and complexity characteristic of these wines. Sauvignon Blanc contributes acidity and freshness, balancing the sweetness, while Muscadelle adds aromatic qualities, enhancing the wine's overall bouquet. This specific combination is what defines Sauternes and differentiates it from sweet wines made in other regions or from other grape varieties.

Other grape varieties mentioned in the incorrect options, like Chardonnay or Riesling, are renowned in their own right but do not play a significant role in the creation of Sauternes. This emphasizes the unique terroir of the Bordeaux region and the specific characteristics of the grape varieties used to craft this exquisite wine.
