C \([-1,0]\)
D \([0,\pi]\)

Correct Answer
A. \([-1,1]\)
Explanation
Simple Explanation
अंतराल \([0,\pi]\) में \(\cos x\) लगातार घटता है: \(\cos 0=1\) और \(\cos\pi=-1\)। इसलिए इस अंतराल में \(\cos x\) के सभी मान \(-1\) से \(1\) के बीच आते हैं और दोनों सिरों के मान शामिल हैं; अतः परिसर \([-1,1]\) है। परीक्षा में \([0,\pi]\) पर cosine का मान-परास याद रखें: \([-1,1]\)। / On the interval \([0,\pi]\), \(\cos x\) decreases continuously from \(\cos 0=1\) to \(\cos\pi=-1\). Since both endpoints are included, every value from \(-1\) to \(1\) is attained, so the range is \([-1,1]\). Exam tip: for cosine over \([0,\pi]\), check the endpoint values first; they give the complete range.
