Answer:
Safety.
Step-by-step explanation:
In physiological studies, Maslow's hierarchy of needs refers to the motivational theory containing a five-stage structure of human needs, which are displayed in hierarchical stages inside a pyramid. These needs starting at the lowest level of the hierarchy to upward start from physiological to safety then love followed by esteem and at last self-actualization. The most basic needs lie at the lowest levels of the hierarchy and as we move upward they become more complex.
