Correct answer: (d) 1, 2 and 3 are correct
Explanation
- A
1 and 2 only
(a) 1 and 2 only. Drops statement 3. Siwalik beds do yield remains associated with early humans and later settlements; omitting 3 is incomplete against the stored key.
- B
2 and 3 only
(b) 2 and 3 only. Drops statement 1. Greater Himalayan sedimentary/metamorphic piles are classed as largely unfossiliferous in this syllabus pairing.
- C
1 and 3 only
(c) 1 and 3 only. Drops the Lesser Himalayan marine-fossil limb, which the key treats as correct.
- D
1, 2 and 3 are correct
(d) 1, 2 and 3 are correct. Greater Himalayan rocks are treated as fossil-free; Lesser Himalayan sediments carry marine fossils; Outer/Siwalik Himalaya holds remains of human civilisation (and rich vertebrate fossils). All three limbs are keyed true.
Summary. Official key is (d) 1, 2 and 3. The three Himalayan belts are given three fossil stories: Greater unfossiliferous, Lesser marine fossils, Siwalik human-civilisation remains. No limb is dropped. Honour the stored letter (d).
