Which transformation captures the essence of the original statement regarding daily activities?

The correct choice effectively embodies the essence of the original statement by indicating a habitual action. When discussing daily activities, it is crucial to convey that these actions occur regularly rather than being confined to a specific moment in time.

In this case, stating "I walk to school every day" clearly communicates that walking to school is a consistent part of the speaker's routine. This phrase captures the frequency and nature of the activity, aligning it with the idea of daily activities.

The other choices, while implying some form of walking, either specify a particular timeframe or lack the repetition aspect inherent in the original statement. For instance, stating "I was walking to school last week" points to a past occurrence, and "I am walking to school regularly" introduces an element of variability rather than emphasizing the daily commitment. Thus, the choice that reflects a consistent daily behavior is the one that accurately transforms the original statement.
