If \(A=\{1,2,{1,2}\}\) then which statement is false?
Explanation opens after your attempt
Correct Answer
C. \({1,2}\subseteq A\)
Concept
This set has (1), (2), and ({1,2}) as elements. All four statements are actually true, so this question checks careful reading.
Why this answer is correct
The correct answer is C. \({1,2}\subseteq A\). This set has (1), (2), and ({1,2}) as elements. All four statements are actually true, so this question checks careful reading.
Exam Tip
({1,2}) (A) का अवयव है, पर इसके अवयव (1,2) से बना समुच्चय (A) का उपसमुच्चय भी हो सकता है; यहां विकल्प असत्य नहीं है। सही असत्य विकल्प नहीं दिखता, इसलिए ध्यान दें कि सभी दिए कथन सत्य हैं।
