अरबी समुद्र आणि सह्याद्री पर्वत यांच्या दरम्यान ______ हा प्राकृतिक विभाग आढळतो.

The correct answer is Option D (Kokan Coast).

Key Points:
• Konkan Coastal Lowland of Maharashtra:
• Physiographic Division: The Konkan coastal lowland is the narrow coastal strip of land situated between the Arabian Sea to the west and the Sahyadri Mountain Range (Western Ghats) to the east.
• Dimensions & Extent: It extends roughly 720 km north-to-south from the Damanganga River in the north to the Terekhol River in the south.
• Width: Highly uneven, wider in the north (around 90–95 km in Palghar/Thane) and narrowest in the south (around 40–45 km in Sindhudurg).
• Topography: Characterized by steep westward-flowing short and swift rivers, tidal creeks (खाड्या), estuaries, pocket beaches, and lateral sea cliffs.
• It is divided geomorphologically into 'Khalaati' (lowland near the coast) and 'Valaati' (upland terraced foothills near Sahyadri).
• Key Takeaway: The Konkan Coast is the physiographic natural division nestled between the Arabian Sea and the Sahyadri mountain range.
