Accepted Answer

Sol. [Key Concept: Geological eras and animal groups]The intended broad matching is Mesozoic–birds and reptiles (A–III), Proterozoic–early lower invertebrates (B–I), Cenozoic–mammals (C–IV), and Palaeozoic–fishes and amphibians (D–II). Hence, option (2). These are broad textbook associations with appearance or diversification; they do not mean that each group originated and existed only within the matched era.
