1. **Justification for Option 2 (V. R. Patvardhan):**
   - V. R. Patvardhan is a renowned figure in the field of Indian classical music, particularly known for his contributions to the study and documentation of ragas. His work 'Raga-Vigyan' is a significant text that delves into the intricacies of ragas, providing a comprehensive analysis and understanding of their structure and performance. This text is well-regarded among musicians and scholars for its depth and clarity, making V. R. Patvardhan the correct author of 'Raga-Vigyan'.

2. **Explanation for why other options are incorrect:**

- **Option 1 (V. D. Paluskar):**
     - V. D. Paluskar was a prominent Indian classical musician and a pioneer in the field of music education. He is best known for founding the Gandharva Mahavidyalaya, a music school that played a crucial role in popularizing Hindustani classical music. However, he is not credited with authoring 'Raga-Vigyan'.

     - V. N. Bhatkhande was a distinguished musicologist who made significant contributions to the codification and systematization of Hindustani classical music.

- **Option 4 (Ravi Shankar):**
     - Ravi Shankar was an internationally acclaimed sitar virtuoso and composer, known for his role in popularizing Indian classical music worldwide. While he authored works related to his musical experiences and compositions, he is not associated with the authorship of 'Raga-Vigyan'.

In conclusion, the correct answer is Option 2, V. R. Patvardhan, as he is the rightful author of 'Raga-Vigyan', and the other options do not align with the authorship of this particular text.
