Answer 1

The Correct Option is A

Concept:
Adam Smith is known as the father of modern economics. He supported the idea that markets can coordinate economic activities through self-interest and competition. His famous concept of the invisible hand explains how private self-interest may promote social welfare.
Step 1: Check statement A.
The invisible hand means individuals pursue their own self-interest, but their actions can indirectly promote social welfare. So: \[ A = \text{Correct} \]
Step 2: Check statement B.
Adam Smith did not argue that government intervention is essential for regulating markets for efficiency. He generally supported free markets and limited government intervention. So: \[ B = \text{Incorrect} \]
Step 3: Check statement C.
Smith emphasized productivity, division of labour and efficiency as important sources of national wealth. So: \[ C = \text{Correct} \]
Step 4: Check statement D.
Modern economists have developed Smith's ideas further. They also recognize the role of macroeconomic policies in managing employment, inflation, growth and stability. So: \[ D = \text{Correct} \]
Step 5: Final conclusion.
The correct statements are: \[ A,\ C,\ D \] Hence: \[ \boxed{\text{(A) A, C, D only}} \]
