Question

Which of the following is a pair of parallel lines

$\left(a\right)$ Lines $a$ and $b$ have 2 common points
$\left(b\right)$ Lines $m$ and $n$ have 0 common point
$\left(c\right)$ Lines $m$ and $n$ have 1 common point

• A. $\left(i\right)$ and $\left(ii\right)$ only
• B. $\left(ii\right)$ only
• C. $\left(ii\right)$ and $\left(iii\right)$ only
• D. $\left(i\right),\left(ii\right)$ and $\left(ii\right)$ only

Answer 1

The correct option is B $\left(ii\right)$ only

Parallel lines do not have a point in common.
$\therefore$ $\left(ii\right)$ Lines $m$ and $n$ have 0 common point is correct.
