Concept
(A) has (2) elements and (B) has (2) elements, so \(2\times 2=4\) options are formed. Real-life choices can also be counted by Cartesian product.
Why this answer is correct
The correct answer is C. (4) विकल्प / (4) options. (A) has (2) elements and (B) has (2) elements, so \(2\times 2=4\) options are formed. Real-life choices can also be counted by Cartesian product.
Exam Tip
(A) में (2) और (B) में (2) तत्व हैं, इसलिए \(2\times 2=4\) विकल्प बनते हैं। वास्तविक जीवन के चुनाव भी कार्तीय गुणन से गिने जा सकते हैं।
