Answer 1

The correct option is D Animals are bilaterally symmetrical

The phylum Ctenophora includes animals that exhibit bioluminescence and have comb plates for the purpose of locomotion. They are hermaphrodites since the sexes are not separate. They exhibit sexual mode of reproduction only. They are found to be exclusively marine. Organisms belonging to this phylum are diploblastic and have tissue level of organisation. They are radially symmetrical.
