Select the correct indirect form of the given sentence.

Mahesh said to Rita, "Don't play in the sun."

Mahesh advised Rita not to play in the sun.

The correct indirect form of the given sentence is:

Mahesh advised Rita not to play in the sun.

The other options are incorrect:

• Mahesh told to Rita to not play in the sun. - This is incorrect because the preposition "to" is unnecessary in this context.
• Mahesh requested Rita that don't play in the sun. - This is incorrect because the modal verb "don't" in the reported speech is grammatically incorrect.
• Mahesh ordered Rita that not play in the sun. - This is incorrect because the verb "ordered" suggests that Mahesh was giving Rita a command, but the original sentence is a prohibition against playing in the sun in the first place.
