Assertion :If...

Question

Assertion :If the polar of a point $A$ passes through $B$ , then the polar of $B$ passes through $A$ and points $A$ and $B$ are called conjugate points. Reason: If the pole of a line $l_{1}$ lies on $l_{2},$ then the pole of line $l_{2}$ lies on $l_{1},$ and these lines are called conjugate lines.

Solution

The correct option is B Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
$\Rightarrow$ If the polar of the point A passes through B, then the polar of B passes through A and pts. A and B are called conjugate points - TRUE

$\Rightarrow$ If the pole of a line $l_{1}$ lies on $l_{2}$ the pole of $l_{2}$ lies on $l_{1}$ , and these lines are called conjugate lines - TRUE

Both Assertion and Reason are correct but Reason is not correct explanation for Assertion.
