In the process of gastrulation, the termination of this developmental stage is typically associated with the elimination of the blastocoel, which is the fluid-filled cavity in the early embryo. Gastrulation involves the formation of three germ layers and the rearrangement of cells to establish the basic body plan of the organism.

The "Elimination of blastocoel," correctly identifies the event that marks the end of gastrulation. As the cells migrate and differentiate, the blastocoel is gradually reduced and eventually disappears, giving way to the formation of the three germ layers.

Therefore, option 1 is the correct answer.
