Correct option is: (B) \(\sqrt{119}\) cm.
\(\because\) OP \(\perp\) PQ (Radius and tangent are perpendicular at point of contact)
= \(\angle\) OPQ = 90°
Now, in right \(\triangle\) OPQ
\(PQ^2 = OQ^2 - OP^2 = 12^2 - 5^2 \)
= 144 - 25 = 119
\(\therefore\) PQ = \(\sqrt{119}\) cm
Hence, length of tangent PQ is \(\sqrt{119}\) cm.
