Diploblastic and triploblastic are terms that describe

Athe number of invaginations during embryonic development
Bthe number of heads during embryonic development
Cthe number of germinal layers during embryonic development
Correct Answer
Dthe number of cell types during development

Solution

Diploblastic animals have two germinal layers (ectoderm and endoderm) during embryonic development, e.g., poriferans. Triploblastic animals have three germinal layers (ectoderm, mesoderm and endoderm) during embryonic development, e.g., platyhelminthes.
Hence the correct option is C.
