Answer is Wrong!
Answer is Right!
The correct answer is D.
Robbins’ definition of economics is “the science of human behavior as a relationship between ends and scarce means which have alternative uses.” This means that economics is the study of how people make choices when they have limited resources.
Option A is incorrect because it is a definition of economics given by Adam Smith.
Option B is incorrect because it is too broad. Economics is not just the study of the ordinary business of human life. It is also the study of how people make choices when they have limited resources.
Option C is incorrect because it is not a definition of economics.
