The appropriate sequence of numbered animals from column-$II$ matching with the sequence of larvae in column-$I$ is

Column-$I$	Column-$II$
$(a)$. Planula	$(i)$. Mussel
$(b)$. Glochidium	$(ii)$. Crab
$(c)$. Nauplius	$(iii)$. Obelia
$(d)$. Cysticercus	$(iv)$. Nereis
	$(v)$. Taenia solium

Consider the following features:
$(a)$ Organ system level of organisation
$(b)$ Bilateral symmetry
$(c)$ True coelomates with segmentation of body
Select the correct option of animal groups which possess all the above characteristics.

$A$: Piscean scales are similar to reptilian scales in origin.
$R$: Age of the animal can be deduced by lines of growth on both the scales.

Match the following columns:

Column-$I$	Column-$II$
$I.$ Skin without scales	$p.$ $Catla$
$II.$ Placoid scales	$q.$ $Hagfish$
$III.$ Cycloid scales	$r.$ $Chameleon$
$IV.$ Epidermal scales	$s.$ $Ray-fish$

Match the following group of organisms with their respective distinctive characteristics and select the correct option:

Organisms	Characteristics
$(a)$ Platyhelminthes	$(i)$ Cylindrical body with no segmentation
$(b)$ Echinoderms	$(ii)$ Warm-blooded animals with direct development
$(c)$ Hemichordates	$(iii)$ Bilateral symmetry with incomplete digestive system
$(d)$ Aves	$(iv)$ Radial symmetry with indirect development
