Correct Answer: Nita says that she has heard the podcast before.

Solution : The right choice is the third option .

The steps of conversion are as follows:

• There would be no change in the reporting verb.
• There would be no change in the tense of the reported clause, as the reporting verb is in the simple present tense.
• The first-person pronoun "I" is changed to the third-person pronoun "she".
• The connector "that" is used to introduce the reported clause.

Therefore, the indirect statement would be: "Nita says that she has heard the podcast before."
