Neurulation is the process during embryonic development where the neural tube, which will give rise to the central nervous system, is formed. It is a critical stage in establishing the bilateral symmetry of mammals. During neurulation, the ectoderm in the dorsal midline region of the embryo folds inward to form the neural plate. The neural plate then undergoes further folding and fusion to create the neural tube.
The neural tube divides the embryo into two halves, establishing bilateral symmetry. The anterior (head) and posterior (tail) ends of the neural tube will give rise to the brain and spinal cord, respectively. The formation of the neural tube and the establishment of bilateral symmetry are important milestones in early embryonic development.
Therefore, the correct answer is A. Neurulation.

Neurulation:
Neurulation is the embryological stage in mammals that divides the embryo in two halves, establishing bilateral symmetry. This process occurs during the third week of gestation in humans.
Importance of Neurulation:
Neurulation is a crucial stage of development as it marks the beginning of the formation of the nervous system. During neurulation, the neural plate folds in on itself to form the neural tube, which gives rise to the brain and spinal cord. This process also establishes the left-right axis of the organism, leading to bilateral symmetry.
Establishing Bilateral Symmetry:
Neurulation is responsible for establishing bilateral symmetry in mammals. Bilateral symmetry means that an organism can be divided into two equal halves along a single plane, resulting in mirror images. This symmetry is essential for the proper development and functioning of complex organisms like mammals.
Conclusion:
In conclusion, neurulation is the embryological stage in mammals that divides the embryo in two halves, establishing bilateral symmetry. This process is critical for the formation of the nervous system and the overall development of the organism.
