Correct Answer

B. \(4!\)

Explanation

Simple Explanation

क्रमगुणित में \(n!=n\times(n-1)\times\cdots\times1\)। अतः \(4!=4\times3\times2\times1=24\), इसलिए सही विकल्प \(4!\) है। \(3!=6\) होता है, जबकि \(5!=120\) होता है; इसलिए ये 24 के बराबर नहीं हैं। परीक्षा टिप: \(3!=6\), \(4!=24\) और \(5!=120\) जैसे छोटे क्रमगुणित मान याद रखें। / For factorials, \(n!=n\times(n-1)\times\cdots\times1\). Thus, \(4!=4\times3\times2\times1=24\), so \(4!\) is correct. In comparison, \(3!=6\) and \(5!=120\), so neither equals 24. Exam tip: memorise common small factorial values such as \(3!=6\), \(4!=24\), and \(5!=120\).
