Answer 1

Answer:

B. Only 2

Drainage Characteristics: The Indian Desert (Thar Desert) is characterized by an endoreic drainage system, meaning most water bodies are inland and do not reach the sea.

Nature of Streams: Streams in this region are primarily ephemeral, meaning they only flow during the brief and erratic monsoon season. They are not perennial and dry up quickly due to high evaporation rates and porous sandy soil.

Disappearance into Sand: Most streams in the Thar Desert lose their volume rapidly as they flow, eventually disappearing into the extensive sand dunes and sandy plains. They fail to reach an outlet like the ocean or a major river system.

Luni River Exception: The Luni River is the largest river system in the region. It rises in the Aravalli Range and flows southwest through the desert, but it typically ends in the Rann of Kachchh rather than the Arabian Sea, further demonstrating the inland drainage pattern.
