Answer:
Mother said "He has to do his homework now."
Explanation:
When describing something that someone said directly is called direct speech while reporting the same event without the speech marks and not using the exact same words is known as reporting speech. To change between the two requires the change in the tense of the verbs and also some phrases or time words, according to their structure. For example, yesterday is changed to the previous day in the indirect speech and so on.
The given indirect speech "mother said that he had to do his home-work" will be changed into the direct speech as given below-
<u><em>Mother said, "He has to do his home-work now."</em></u>
Here, the apparent changes are the speech marks (" "), the comma after "said", and the change in "then" to "now".
