Answer:
The correct option is:
3. Ankit told Rita that it was her last chance.
Explanation:
This question is about reported speech. When we report what someone has said, it is important to observe a few things.
1. We usually change the verb tense to the past form of the tense used in the original sentence. In this case, the simple present was used. Therefore, the reported version will be in the simple past.
2. The pronouns need to change accordingly. When Ankit said "your", he was talking to Rita. Now that we are reporting what he said, since we are not talking directly to Rita, we should change "your" to "her".
Having that in mind, we can safely make the changes:
Ankit said to Rita, "It is your last chance." - 3. Ankit told Rita that it was her last chance.
