पुढीलपैकी विजातीय स्वर कोणते ?

The correct answer is Option C (उ-ए).

Key Points:
• In Marathi phonetics, vowels are classified into Homogeneous (Sajatiya) and Heterogeneous (Vijatiya) based on their place of articulation.
• Sajatiya Swar: Vowels originating from the same pronunciation origin (e.g., a-aa, i-ii, u-uu).
• Vijatiya Swar: Vowels originating from different pronunciation origins.
• 'u' (lips) and 'e' (throat+palate) have different articulation points, making them Vijatiya. Options 1, 2, and 4 are Sajatiya pairs.
• Key Takeaway: Vowels with different articulation points are called Vijatiya (e.g., u-e, a-i).
