Question

Assertion :i)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: ii)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

If the polar of a point $A$ pases through $B$ and the polar of $B$ passes through $A$ , then points $A$ and $B$ are called conjugate points

If the pole of one line lies on other and the pole of other line lies on first one then these lines are called conjugate lines

Both the above statements are correct but the reason is not correct explanation of the assertion

Therefore the correct option is $B$
