If the pair of linear equations: $a_1x + b_1y + c_1 = 0$ and $a_2x + b_2y + c_2 = 0$ is consistent and dependent, then
- (a)$\frac{a_1}{a_2} \neq \frac{b_1}{b_2}$
- (b)$\frac{a_1}{a_2} = \frac{b_1}{b_2} \neq \frac{c_1}{c_2}$
- (c)$\frac{a_1}{a_2} \neq \frac{b_1}{b_2} = \frac{c_1}{c_2}$
- (d)$\frac{a_1}{a_2} = \frac{b_1}{b_2} = \frac{c_1}{c_2}$
