Step 1: Understanding the Concept:
The question asks to identify which of the listed Tabla Gharanas are known for the 'Khula Baaj' (open playing style).
Step 2: Detailed Explanation:
- (A) Farukhabad, (B) Lucknow, (C) Banaras: These three are known as the 'Purbi' (Eastern) Gharanas and are the primary proponents of the Khula Baaj, which emphasizes resonant, open-handed strokes.
- (D) Punjab: While the Punjab Gharana has its own distinct baaj, it is heavily influenced by the Pakhawaj and is characterized by powerful, open strokes. Therefore, it is also considered a Khula Baaj gharana, distinct from the closed style of Delhi and Ajarada.
Since all four gharanas listed utilize an open playing style as their primary characteristic, all of them can be classified as having 'Khula Baaj'.
Step 3: Final Answer:
All four gharanas—Farukhabad, Lucknow, Banaras, and Punjab—are associated with the Khula Baaj.
