- Popular: Popularmente.

Explanation:

In Spanish, a form to convert adjectives into adverbs is to add the ending "mente" to the adjective with minimal changes in the words (in the exercise, just changed the adjective "rico" by "rica" and added the ending, the others adjectives stayed same), that method is comparable to add the ending "ly" to some adjectives, converting them into adverbs in English like:

- Natural: Naturally.
