Explanation:

Three major geographical entities, the Himadri (greater Himalaya), Himanchal (lesser Himalaya) and the Shiwaliks (outer Himalaya) extending almost uninterrupted throughout its length, are separated by major geological fault lines.

he Himadri (greater Himalaya):The Great Himalayas or Greater Himalayas is the highest mountain range of the Himalayan Range System. ... The total west to east extension of the great Himalayas is 2400 km (1500 miles) and their average elevation is 6000 m (20000 ft.). They are home to many glaciers like Gangotri Glacier, Satopanth Glacier

Himachal (lesser Himalaya):The Himachal Range (Nepali: महाभारत पर्वत शृङ्खला mahāvārat parbat shrinkhalā) – also called the Lower Himalayan Range or Lesser Himalaya – is a major east-west mountain range with elevations 3,700 to 4,500 m (12,000 to 14,500 feet) along the crest, paralleling the much higher High Himalayas range from the Indus River

the Shiwaliks (outer Himalaya):Siwalik Range, also called Siwalik Hills or Outer Himalayas, Siwalik also spelled Shiwalik, sub-Himalayan range of the northern Indian subcontinent. ... Though only 10 miles (16 km) wide in places, the range has an average elevation of 3,000 to 4,000 feet (900 to 1,200 metres)

option c (nickel) is not found in earth's crust. the earth's crust basically contains eight (8) elements namely: oxygen, silicon, aluminum, iron, calcium, sodium, potassium and magnesium (listed in order of abundance).

the correct answer is d.

hope this
