Which is the correct difference in the basic origin of the Himalayas and Deccan Plateau?

Himalayas are linked with compression and Deccan with lava flows

The correct answer is D. The Himalayas are young fold mountains formed when the Indian Plate moved northward and compressed marine and continental sediments against the Eurasian Plate. Their origin is therefore connected with tectonic convergence, folding, uplift, and continuing mountain building. The Deccan Plateau, in contrast, is a broad ancient shield region whose large basaltic areas were produced mainly by extensive volcanic lava flows, especially during the Deccan volcanic episode. Option A reverses or invents origins, while B and C misidentify both landforms. The important comparison is compressional folding for the Himalayas versus volcanic basaltic construction for the Deccan Plateau.
