Correct Answer: Mother said to Avika, “These flowers are not to be thrown today.”

Solution : The fourth option is the correct choice.

Narration Conversion:

• The reporting verb told is changed to said in direct speech.
• Those flowers changes to these flowers , as the words are directly reported.
• That day in reported speech changes to today in direct speech because the words are directly quoted without changing the time frame.

Therefore, the correct sentence is: Mother said to Avika, "These flowers are not to be thrown today."
