  4. D(a)−(i),(b)−(ii),(c)−(iii),(d)−(iv)( a ) - ( i ) , ( b ) - ( ii ) , ( c ) - ( iii ) , ( d ) - ( iv )

Correct answer

A. (a)−(iii),(b)−(iv),(c)−(i),(d)−(ii)( a ) - ( iii ) , ( b ) - ( iv ) , ( c ) - ( i ) , ( d ) - ( ii )

Step-by-step solution

Organisms Characteristics
Platyhelminthes They are triploblastic, acoelomates having bilateral symmetry with the incomplete digestive system.
Echinoderms Adults show pentaradial symmetry, while the embryonic show bilateral symmetry. The mode of embryonic development is indirect.
Hemichordates They are triploblastic, coelomates having cylindrical bodies with no segmentation
Aves Aves and mammals have a four-chambered heart, that prevents the mixing of oxygenated and deoxygenated blood and hence are warm-blooded. The mode of embryonic development is direct.
