Correct Answer

B. \(\cosec \theta\)

Explanation

Simple Explanation

\(\sin \theta\) का व्युत्क्रम \(\dfrac{1}{\sin \theta}\) होता है। परिभाषा के अनुसार \(\cosec \theta=\dfrac{1}{\sin \theta}\), इसलिए सही विकल्प \(\cosec \theta\) है। \(\sec \theta\), \(\cos \theta\) का व्युत्क्रम होता है, जबकि \(\cot \theta\), \(\tan \theta\) का व्युत्क्रम है। परीक्षा टिप: व्युत्क्रम युग्म याद रखें—sin–cosec, cos–sec और tan–cot। / The reciprocal of \(\sin \theta\) is \(\dfrac{1}{\sin \theta}\). By definition, \(\cosec \theta=\dfrac{1}{\sin \theta}\), so \(\cosec \theta\) is the correct option. \(\sec \theta\) is the reciprocal of \(\cos \theta\), whereas \(\cot \theta\) is the reciprocal of \(\tan \theta\). Exam tip: Remember the reciprocal pairs: sin–cosec, cos–sec, and tan–cot.
