'कोण', 'काय' ही सर्वनामे खालील कोणत्या प्रकारांत येतात ?

The correct answer is Option A (प्रश्नार्थक व अनिश्चित).

Key Points:
• The pronouns 'Kon' and 'Kay' have a dual function in Marathi grammar depending on their context.
• Interrogative (Prashnarthak): When used to ask a clear question. (e.g., Kon aale? - Who came?).
• Indefinite (Anishchit/Samanya): When they are used in a sentence but not to ask a question, and it is indefinite who or what they refer to. (e.g., Tya peti madhye kay ahe, te mala mahit nahi - I don't know what is in that box).
• Therefore, they fall under both Interrogative and Indefinite pronoun categories.
• Key Takeaway: 'Kon' and 'Kay' function as Interrogative pronouns in questions and Indefinite pronouns in declarative statements.
