Solution

The correct option is A Obliteration of blastocoel
Termination of gastrulation

During gastrulation, blastocyst transforms into the gastrula and the blastocoel is replaced by the archenteron.

Thus, obliteration of blastocoel is marked by the termination of gastrulation.

Final answer:

(a) Obliteration of blastocoel
