• B. Fondant is a fat-based emulsion; buttercream is a sugar paste for a smooth finish.
• C. Fondant and buttercream are the same.
• D. Fondant is used for fillings; buttercream only for icing on surfaces.

Answer: (A)

Fondant and buttercream differ in both what they’re made from and how they’re used on a cake. Fondant is a sugar paste that you roll out and drape over a cake to create a very smooth, polished finish. It forms a thin, malleable shell that gives a sleek exterior. Buttercream is a fat-based emulsion, typically butter or shortening beaten with sugar and a liquid, which yields a creamy, spreadable icing that can also be piped or used as a filling. This combination explains why fondant is preferred for a smooth exterior, while buttercream provides flavor, texture, and versatility for both filling and icing. The other ideas don’t fit: fondant isn’t a fat-based emulsion, they aren’t the same substance, and fondant isn’t typically used as a filling in the same way buttercream is.
