The correct answer is option 4, which means that Tulsidas was the author of Ramcharitmanas and Kavitavali only.

Let`s break down the options to understand them better:

- Option 1: "1 only" means that Tulsidas was the author of Ramcharitmanas only. This contradicts the correct answer, as Tulsidas also authored Kavitavali.

- Option 2: "2 and 3 only" suggests that Tulsidas was the author of Padavali and Kavitavali. However, this is not correct as Tulsidas` work, Padavali, is not listed as one of the options.

- Option 3: "1, 2, and 3" implies that Tulsidas was the author of all three options: Ramcharitmanas, Padavali, and Kavitavali. However, as we discussed earlier, Tulsidas is not the author of Padavali.

- Option 4: "1 and 3 only" states that Tulsidas was the author of Ramcharitmanas and Kavitavali only. This aligns with the correct answer, so option 4 is the correct choice.
