Correct Answer

A. \([-4,4]\setminus{1}\)

Explanation

Simple Explanation

वर्गमूल के लिए \(16-x^2\ge 0\), यानी \(-4\le x\le 4\), और हर के लिए \(x\ne 1\) चाहिए। प्रांत इन शर्तों का प्रतिच्छेद है। / The square root needs \(16-x^2\ge 0\), meaning \(-4\le x\le 4\), and the denominator needs \(x\ne 1\). The domain is the intersection of these conditions.
