What is the reported speech for "I will call you tomorrow," she said?

The correct option reflects the proper application of reported speech when converting a direct statement into indirect speech. In this case, the original statement is future tense ("I will call you tomorrow"), which must be adjusted when changing it to reported speech. The transformation correctly shifts "will" to "would," as this reflects the change in timeframe when reporting someone's future intention in the past tense.

Using "she told me" appropriately indicates that the information was conveyed directly to the speaker, and "she would call me tomorrow" maintains the intended meaning of the original statement while adhering to the grammatical rules of reported speech. This transformation is essential in retaining the speaker’s original intent while adapting the tense and structure to fit the reported format.

The other options, while attempting to express the same idea, do not utilize the correct tense or structure required for reported speech. Therefore, the selected answer accurately encapsulates the original statement in a grammatically correct manner.
