Which deep-fried dough is filled with jam or cream and often dusted with powdered sugar?

The correct choice is the one that accurately describes a deep-fried dough filled with jam or cream and typically dusted with powdered sugar. This description aligns perfectly with zeppole, which are Italian desserts often made for special occasions and feature a dough that can be filled with a variety of sweet fillings like ricotta, custard, or jam. After frying, they are frequently topped with powdered sugar, enhancing their sweetness and visual appeal.

Churros, while a delicious fried dough, are usually served plain or with chocolate sauce for dipping rather than filled. Funnel cake is distinct in its appearance and preparation, being a tangled web of fried pastry rather than a filled donut. Donuts, while also deep-fried and often covered in powdered sugar, do not align as closely with the typical fillings specified, as they are more commonly glazed or frosted rather than filled with jam or cream.

Understanding these elements helps clarify why zeppole is the right answer in relation to the properties and characteristics of the specific desserts mentioned.
