Step 1: Understanding scientific management. 
  
In scientific management, the goal is to produce the maximum output with the minimum effort. This is achieved through methods like time and motion studies, standardization of work processes, and specialization of tasks. The focus is on maximizing efficiency while minimizing wasted resources. 
Step 2: Analyzing the options. 
  
(A) Maximum: Incorrect. Although scientific management aims to maximize efficiency, the correct emphasis is on minimizing resources used, not maximizing output. 
  
(B) Minimum: Correct. Scientific management emphasizes the minimum use of resources, time, and effort to achieve optimal productivity. 
  
(C) Normal: Incorrect. Normal production is not the specific focus of scientific management. The focus is on optimization and efficiency. 
  
(D) None of these: Incorrect. Option (B) is the correct answer. 
Step 3: Conclusion. 
  
The correct answer is (B) Minimum, as scientific management focuses on minimizing the resources and effort used in production.
