The question is about matching authors with their respective texts. The correct answer option is number 2,

Option 1 suggests that Sudraka wrote `Vikramankadevacharita` and Bilhana wrote `Mrchchhakatikam` - this is incorrect as Sudraka is known for `Mrchchhakatikam` and Bilhana is known for `Vikramankadevacharita`.

Option 2 is accurate. It matches each author correctly with their works: Varahamihira with `Brhat-Samhita`, Visakhadatta with `Devi Chandraguptam`, Sudraka with `Mrchchhakatikam`, and Bilhana with `Vikramankadevacharita`.

Option 3 suggests Sudraka wrote `Devi Chandraguptam` and Visakhadatta wrote `Brhat-Samhita`, which is inaccurate.

Option 4 is also incorrect as it suggests Varahamihira wrote `Prabandha Chintamani` and Visakhadatta wrote `Brhat-Samhita`.
