Final answer:
Mahon is the cheese that is not made from goat's milk among the options listed; it is made from cow's milk, whereas the other cheeses mentioned are all made from goat's milk.
Step-by-step explanation:
The question is asking which of the listed cheeses is not made from goat's milk. After evaluating the cheeses listed, it's clear that Mahon is the one that is not a goat's milk cheese. Mahon is a cheese that comes from the island of Menorca in Spain, and it is primarily made from cow's milk. On the other hand, Dona Julia, Garrotxa, and Cana de Cabra are all cheeses made from goat's milk. Dona Julia is a Portuguese goat cheese with a firm texture, Garrotxa is a Spanish goat cheese with a natural rind and semi-firm texture, and Cana de Cabra is also a Spanish goat cheese that's soft-ripened and has a fine, creamy texture. Thus, the cheese not made from goat's milk in this selection is Mahon.
