Answer: C. Physiological
Explanation: According to Abraham Maslow's theory, there is a hierarchy of human needs from which motivations to meet those needs emerge. At the lowest level of the hierarchy or pyramid are the physiological needs that must first be met. These are physiological needs for food, sleep and other physiological needs, also called lower needs.
After satisfying the physiological needs of the individual, there follows the needs for security, love, belonging, etc., and so on to the top of the pyramid, where there are needs for socialization of self-proofing, acquisition of social status, etc.
