Choose the correct match showing division of labour with animal example:

‘Cephalization’ in animals was facilitated by evolution of:
1. Radial symmetry
2. Tissue grade organization
3. Bilateral symmetry
4. True coelom

Identify the correct statement:
1. All pseudocoelomates are protostomes
2. All bilaterally symmetrical animals have a coelom

1. Anterior and posterior end
2. Right and left half
3. Dorsal and ventral surface
4. Oral and aboral surface

3. Molluska
4. Hemichordata

1. Snail
2. Earthworm
3. Sea urchin
