Explanation | व्याख्या |
Option (a) is correct. Statement C "Some mushrooms are fungi" and statement D "Some mushrooms are not fungi" are related in a way that they cannot both be false, although they may both be true. If some mushrooms are fungi (statement C), then it is logically necessary that some mushrooms are not fungi (statement D) because the two statements are complementary. If all mushrooms were fungi (statement A), then statement D would be false. Similarly, if no mushrooms were fungi (statement B), then statement C would be false. However, since the statements C and D are related in this complementary manner, they cannot both be false. Therefore, the correct answer is option (a) C and D only. विकल्प (a) सही है। जब दो कथन आपस में उप-विरोधी हो तो दोनों एक साथ सही हो सकते, यद्यपि वे दोनों असत्य नही हो सकते हैं। कुछ मशरूम कवक है ‘I’ प्रकार का वाक्य है कुछ मशरूम कवक नहीं है ‘O’ प्रकार का वाक्य है। दोनों आपस में उप-विरोधी है। ![]() |
