Answer 1

The correct option is D 1, 2, & 3

During summer, land areas in and around the Indian subcontinent get heated up, creating a low-pressure zone. High-pressure region develops around the island of Madagascar. During the summer months, from March to May, due to the apparent northward movement of the Sun, the ITCZ shifts northwards over the Ganga Plains. This creates a low-pressure region over here.The Tibetan Plateau, north of the Himalayas, also gets heated a lot, intensifying this low pressure. Thus it facilitates the onset of monsoon.
