Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: Symmetricसममित
Step 1: If (a+b=5), then (b+a=5) as well. Step 2: Therefore the reverse of every related pair also belongs to the relation. Step 3: The key signal is that changing the order does not change the sum.चरण 1: यदि (a+b=5), तो (b+a=5) भी होगा। चरण 2: इसलिए किसी भी युग्म का उलटा भी संबंध में रहेगा। चरण 3: जोड़ में क्रम बदलने से योग नहीं बदलता, यह मुख्य संकेत है।
