Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R):
In light of the above statements, choose the correct answer from the options given below:
नीचे दो कथन दिए गए हैं, एक को अभिकथन (Assertion A) और दूसरे को कारण (Reason R) के रूप में लेबल किया गया है:
उपरोक्त कथनों के आलोक में, नीचे दिए गए विकल्पों में से सही उत्तर चुनें:
Assertion (A) is true: According to Jean Piaget, children aged 7 to 11 years are in the Concrete Operational stage, during which they acquire the concept of conservation (understanding that physical properties like mass, volume, and substance remain the same despite superficial changes in outward appearance or shape).
Reason (R) is false: Children in the concrete operational stage CAN reverse their thinking. Reversibility (the mental capacity to undo an action or imagine an object returning to its original state) is precisely the cognitive mechanism that enables conservation. It is preoperational children (ages 2-7) who lack reversibility.
अभिकथन (A) सत्य है क्योंकि 9 वर्ष के बच्चे पियाजे की मूर्त-संक्रियात्मक अवस्था में होते हैं और 'संरक्षण' (conservation) का गुण सीख लेते हैं। कारण (R) असत्य है क्योंकि मूर्त संक्रियात्मक बच्चे अपने विचारों को उलट सकते हैं (Reversibility पाई जाती है)। अतः A सत्य है लेकिन R असत्य है।
