Final answer:
c) Chardonnay, Pinot Noir, Pinot Meunier. The three Champagne varietals are Chardonnay, Pinot Noir, and Pinot Meunier.
Step-by-step explanation:
The correct answer is c) Chardonnay, Pinot Noir, Pinot Meunier. These are the three varietals used in making Champagne.
Chardonnay is a white grape variety, while Pinot Noir and Pinot Meunier are both black grape varieties. Champagne is made by blending these three varietals in different proportions, although some Champagnes may be made from a single varietal.
Chardonnay contributes elegance and citrus flavors to Champagne, while Pinot Noir adds body and fruitiness. Pinot Meunier provides a roundness and aromatic quality to the blend.
