The correct answer is C. motion study.
Motion study is the study of the efficient use of human and mechanical effort in the performance of a task. It is a branch of industrial engineering that seeks to improve productivity by analyzing the movements involved in a task and identifying ways to eliminate unnecessary or inefficient movements.
Time study is the measurement of the time required to perform a task. It is used to determine the standard time for a task, which is the amount of time that a qualified worker should take to perform the task at a normal pace.
Work study is a general term that encompasses both motion study and time study. It is used to improve the efficiency of all aspects of a job, including the movements of the worker, the use of tools and equipment, and the layout of the work area.
Fatigue study is the study of the effects of fatigue on worker productivity. It is used to identify ways to reduce fatigue and improve worker performance.
In conclusion, the study relating to the movement of a machine operator and his machine while performing the job is called motion study.
