A region in the \( x-y \) plane is bounded by the curve \( y=\sqrt{25-x^{2}} \) and the line \( y=0 \). If the point \( (a \), a \( +1 \) ) lies in the interior of the region then
(a) \( \mathrm{a} \in(-4,3) \)
(b) \( \mathrm{a} \in(-\infty,-1) \cup(3,+\infty) \)
(c) \( a \in(-1,3) \)
(d) none of these
