Explanation

Based on the theory of Plate Tectonics and NCERT Geography standards:

Statement 1 is correct: The northern boundary of the Indian Plate is defined by the Himalayan mountain range. This is a convergent boundary where the Indian Plate subducts (or collided after the subduction of the Tethys Ocean) under the Eurasian Plate, forming a continent-continent collision zone.
Statement 2 is incorrect: The eastern margin of the Indian Plate extends from the Rakinyoma Mountains in Myanmar towards the Java Trench. The southern boundary is marked by a spreading site (divergent boundary) called the Southeast Indian Ridge, which separates the Indian Plate from the Antarctic Plate. The eastern boundary in the Southwest Pacific is characterized by subduction zones and transform faults, not a spreading ridge lying to the west of Australia.
