If \( a, b \) and \( c \) are the sides of a triangle and \( A, B \) and \( C \) are the angles opposite to \( a, b \) and \( c \) respectively, then \( \Delta=\left|\begin{array}{ccc}a^{2} & b \sin A & c \sin A \\ b \sin A & 1 & \cos A \\ c \sin A & \cos A & 1\end{array}\right| \) is independent of
(a) \( a \)
(b) \( b \)
(c) \( c \)
(d) \( A, B, C \)
