Correct option is B
Frederick Taylor, known as the father of scientific management, introduced the concepts of time and motion studies, piece-rate compensation systems, and the principle of 'a fair day's work for a fair day's pay' to organizations. While Taylor himself did not specifically introduce the 40-hour workweek, his work laid the foundation for efficiency studies and labor practices that eventually influenced work hours and conditions. Taylor's methods aimed at increasing productivity and efficiency by scientifically analyzing work processes and determining the most efficient ways to perform tasks, thereby significantly influencing modern organizational management and industrial engineering.
