The correct answer is: In what way she walked?
Step-by-step explanation
An adverb is a word that modifies a verb, adjective, adverbs, or sentence. Adverbs are words that express circumstances such as place, time, quantity, among others. Adverbs are used in a sentence when you want to describe a situation, place, or another as a response. In the phrase above, the adverb is "softly" because this word is modifying the verb "walked". This means the adverb modifier describes the way, Janice walked, and therefore, the adverb answers to the question "In what way she walked?"
