Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ({(1,a),(2,a),(3,a)})({(1,a),(2,a),(3,a)})
Since (B) has only (a), every domain element maps to (a). All (1), (2), and (3) must be included.(B) में केवल (a) है इसलिए हर प्रांत तत्व (a) से जुड़ता है। सभी (1), (2), और (3) शामिल होने चाहिए।
