Area of triangle formed by the tangents drawn from a point \( P\left(x_{1}, y_{1}\right) \) outside the parabola \( y^{2}=4 a x \) and their chord of contact is
(a) \( \frac{1}{a}\left(y_{1}^{2}-4 a x_{1}\right)^{\frac{3}{2}} \)
(b) \( \frac{1}{2 a}\left(y_{1}^{2}-4 a x_{1}\right)^{\frac{3}{2}} \)
(c) \( \frac{1}{4 a}\left(y_{1}^{2}-4 a x_{1}\right)^{\frac{3}{2}} \)
(d) \( \frac{2}{a}\left(y_{1}^{2}-4 a x_{1}\right)^{\frac{3}{2}} \)
