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.

• A. Both Assertion and Reason are correct and Reason is the correct explanation for Assertion
• B. Both Assertion and Reason are correct but Reason is not the correct explanation for Assertion
• C. Assertion is correct but Reason is incorrect
• D. Both Assertion and Reason are incorrect

Answer 1

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.
