Which one of the following phyla is CORRECTLY matched with its two general characteristics?
Options
- AAnnelida Notochord at some stage and separate anal and urinary openings to the outside
- BEchinodermata Pentamerous radial symmetry and mostly internal fertilization
- CMollusca Normally oviparous and development through a trochophore or veliger larva
- DArthropoda Body divided into head, thorax and respiration by tracheae
Correct answer
C. Mollusca Normally oviparous and development through a trochophore or veliger larva
Step-by-step solution
Annelids are Non Chordates and hence do not possess notochord at any stage. Echinodermata shows pentamerous radial symmetry but fertilization takes place outside the body and this is external fertilization. Mollousca are mostly oviparous and also shows larval stage. In Arthropods the body is divided into head thorax and abdomen.
