Option A is wrong because this word does not exist in the English language.
Option B is wrong because it is an abstract noun.
Option D is wrong because it is the same as the given adjective.
Option C "prettily" is the correct answer. The adverb is formed by adding the suffix "ly" to the adjective "pretty."
