Directions : In the following questions, the Assertions $(A)$ and Reason $(s) \ (R$) have been put forward. Read both the statements carefully and choose the correct alternative from the following:
Assertion : $a_1x + b_1y + c1 =0; a_2x + b_2y + c_2 = 0$ represent parallel line if $\frac{\text{a}_1}{\text{a}_2}=\frac{\text{b}_1}{\text{b}_2}\neq\frac{\text{c}_1}{\text{c}_2}$
Reason : $3x + 4y + 5 = 0$ and $6x + ky + 9 = 0$ represent parallel line if $K= 5$
