Suppose \( x_{1}, x_{2} \) be the roots of \( a x^{2}+b x+c=0 \) and \( x_{3}, x_{4} \) be the roots of \( p x^{2}+q x+r=0 \).
If \( x_{1}, x_{2}, x_{3}, x_{4} \) are in A.P., then common difference of this A.P. is
(a) \( \frac{1}{2}\left(\frac{b}{a}-\frac{q}{p}\right) \)
(b) \( \frac{1}{3}\left(\frac{b}{a}-\frac{q}{p}\right) \)
(c) \( \frac{1}{3}\left(\frac{c}{a}-\frac{q}{p}\right) \)
(d) \( \frac{1}{4}\left(\frac{b}{a}-\frac{q}{p}\right) \)
