The archenteron develops into

• A. blastocoel
• B. endoderm
• C. lumen of the digestive tract

Answer 1

The correct option is C lumen of the digestive tract

Archenteron is the primary cavity which is formed at the initial stage of gastrulation. This cavity begins at the dorsal lip of blastopore which is at the one side of the dividing zygote and then this cavity moves through the zygote to the other side which gives rise to the anus.

So the correct option is 'lumen of digestive tract'.
