Change the sentence given below from Indirect to Direct speech :

Father ordered his son to run :

Father said to his son, "Run".

The given sentence in Indirect speech is: "Father ordered his son to run."

Now, let's convert it into Direct speech:

In Direct speech, we represent the speaker's words exactly as they were spoken. In this case, "Father ordered his son to run" can be directly quoted as what the father said.

So, the correct conversion is: "Father said to his son, 'Run'."

Here, we have the reporting verb "said" followed by the reporting clause "to his son," and then we directly quote the father's command, "Run," enclosed in quotation marks.

The other options are not as accurate or natural:

• "To run" sounds awkward and incomplete as a standalone statement.
• "Father ordered son, 'To Run'" omits the necessary preposition "to" before "his son" and uses the incorrect verb tense ("ordered" instead of "said").
• "I am ordering you run" sounds unnatural. It uses the present continuous tense instead of the simpler past tense ("said") and adds the unnecessary "I am."
