• B. $\left(a\right)-\left(ii\right),\left(b\right)-\left(iii\right),\left(c\right)-\left(i\right),\left(d\right)-\left(iv\right)$
• C. $\left(a\right)-\left(i\right),\left(b\right)-\left(iii\right),\left(c\right)-\left(ii\right),\left(d\right)-\left(iv\right)$
• D. $\left(a\right)-\left(iii\right),\left(b\right)-\left(ii\right),\left(c\right)-\left(iv\right),\left(d\right)-\left(i\right)$

Answer 1

The correct option is A $\left(a\right)-\left(iii\right),\left(b\right)-\left(i\right),\left(c\right)-\left(iv\right),\left(d\right)-\left(ii\right)$

Answer is option A i.e. "(a)−(iii), (b)−(i), (c)−(iv), (d)−(ii)"
Ostracoderms are the early (extinct) jawless fish of the Paleozoic era.
Coelacanth contains only few living fishes like lobe-finned fishes.
Cyclostomes are living jawless fishes including hagfishes and lampreys.
Osteichthyes are bony fishes e.g. Exocoetus whose body is covered with bony cycloid scales.
