Solution:

Option(C) is correct.
To Find:The range of \sec ^{-1}(x)
Here,the inverse function is given by y=f^{-1}(x)
The graph of the function y=\sec ^{-1}(x) can be obtained from the graph of Y=\sec x by interchanging x and y axes.i.e, if (a, b) is a point on Y=\sec x then (b, a) is the point on the function y=\sec ^{-1}(x)
Below is the Graph of the range of \sec ^{-1}(x)


From the graph, it is clear that the range of \sec ^{-1}(x) is restricted to interval
[0, \pi]-\left\{\frac{\pi}{2}\right\}
