What topping is found in the Moules frites dish?

Moules frites, a classic dish from Belgium, traditionally consists of mussels cooked in a broth, often flavored with ingredients such as garlic, shallots, white wine, herbs, and sometimes chives. Chives are frequently used as a garnish, adding a mild onion-like flavor that complements the dish's richness without overpowering the delicate taste of the mussels. This makes chives a fitting and common topping for moules frites, enhancing both the presentation and flavor profile of the dish.

The other options do not align with the traditional accompaniments used in this dish. Pecans, pickled enoki, and almonds are not typically associated with moules frites, as they do not contribute the same flavor or textural balance that chives provide in this context.
