Amit's dialogue involves asking his sister, Ananya, a question about her certainty in reaching the railway station by herself. Ananya's response affirms her confidence and mentions that she has already booked a cab. When transforming this dialogue into reported speech, it's crucial to adjust the verbs to reflect the past tense since reported speech states what someone said at an earlier time. Below is the breakdown:
- The phrase "are you sure you can" is in the present tense and needs to be changed to past tense as "was sure she could."
- The word "manage" stays the same as it follows the secondary modal "could."
Therefore, the correct option to transform the dialogue into reported speech is: "Amit asked Ananya
if she was sure she could manage to go to the railway station on her own. Ananya replied in the affirmative and said that she had already booked a cab."
