Match List I with List II with respect to chronology of evolution of life forms List-I A. About 65 mya B. About 500 mya C. About 350 mya D. About 320 mya List-II (I) Jawless fish probably evolved (II) The dinosaurs suddenly disappeared from the earth (III) Seaweeds and few plants probably existed (IV) Invertebrates were formed and became active Choose the correct answer from the options given below:
- 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."
