Correct Answer: I asked Aditi if she wasn't afraid of travelling alone in a foreign country.

Solution : The correct choice is the second option.

Indirect speech, also known as reported speech or indirect discourse, is a way of reporting what someone else has said without quoting their exact words.

Narration conversion:

• Change the reporting verb from "said" to "asked".
• In yes-or-no questions, the connector "if/whether" is used to introduce the reported clause in order to convert the questions into statements.
• Introduce the reporting clause with "if".
• Change the second-person pronoun "you" to the third-person pronoun "she" to match the perspective of Aditi in the reported speech.
• Change the demonstrative pronoun "this" to "that" to indicate the shift in time and place.

Therefore, the correct answer is: I asked Aditi if she wasn't afraid of travelling alone in a foreign country.
