Correct Answer: Anju said to her brother, "I am going to bake a cake for you today."

Solution : The correct answer is the third option.

In transforming a sentence from reported speech to direct speech, it is essential to adjust the pronouns and verb tenses appropriately.

The steps of conversion are as follows:

• The reporting verb "told" is changed to "said".
• The third person pronoun "she" is changed to the first person pronoun "I".
• The past continuous tense "was going" is changed to the present continuous tense "am going".
• The time phrase "that day" is changed to "today".
• The words of the speaker are enclosed in the inverted commas.

Therefore, the direct speech would be: Anju said to her brother, "I am going to bake a cake for you today."
