Answer:
The correct answer is letter "B": Systems Thinking.
Explanation:
Based on the ideas of British Scientific Manager Peter Checkland (born in 1930) in his book "Systems Thinking, Systems Practice" (1981), Systems Thinking is an analysis focusing on a system's parts and the way they interrelate to work among them over certain periods as a whole system. Systems Thinking is used in environmental, political, educational, and medical research.
