The correct answer effectively uses the adverb "badly" to modify the verb "affect." In English grammar, adverbs are typically employed to describe verbs, adjectives, or other adverbs, providing details on how an action is performed.

In this instance, "badly" communicates the manner in which the action of affecting is taking place. The sentence indicates that the effect on her is not negative or detrimental. By using "badly" instead of "bad," the sentence follows standard grammatical rules, ensuring clarity and accuracy in the description of the impact.

The other choices incorrectly use "bad" in contexts where "badly," as an adverb, is appropriate. This distinction is essential for maintaining proper syntax and ensuring that the intended meaning is conveyed correctly. This understanding of the application of adverbs versus adjectives is fundamental in achieving precise and effective communication in writing.
