Answer: (D) A(II), B(IV), C(I), D(III). Answer: (D) A(II), B(IV), C(I), D(III).
- A.A(III), B(IV), C(I), D(II)
- B.A(I), B(II), C(III), D(IV)
- C.A(II), B(IV), C(III), D(I)
- D.A(II), B(IV), C(I), D(III)✓
Correct Answer
(D) A(II), B(IV), C(I), D(III)
Solution & Explanation
Answer: (D) A(II), B(IV), C(I), D(III). Matching to the NCERT brief account of evolution: about 65 mya the dinosaurs suddenly disappeared (II); about 500 mya invertebrates were formed and active (IV); jawless fish probably evolved around 350 mya (I); and seaweeds and few plants existed around 320 mya (III). This gives A–II, B–IV, C–I, D–III, which is option (d). NCERT Reference: Ch 6 Evolution, p.122, lines 7–9: "By the time of 500 mya, invertebrates were formed and active. Jawless fish probably evolved around 350 mya. Sea weeds and few plants existed probably around 320 mya."
