Option b is the correct answer. Statement 1 is incorrect - Patanjali's Mahabhashya does not make any direct mention of Kautilya. Kautilya, also known as Chanakya, was a renowned ancient Indian economist, philosopher, and advisor to Chandragupta Maurya. His teachings on statecraft and politics are compiled in the treatise Arthashastra, which is a separate work from Patanjali's Mahabhashya. Statement 2 is correct- Patanjali's Mahabhashya primarily focuses on grammar and linguistic analysis. While it provides explanations and examples related to language, it does not extensively refer to historical personalities or events.
