उत्तर

Assertion (A) is false and Reason (R) is true.

Explanation:

Step 1 – Assertion: A is false. A point lies on the circle only if its distance from the centre equals the radius. Here: $$ PC = \sqrt{(-2 - 3)^2 + (4 - 5)^2} = \sqrt{26} < 6 $$ Thus, P lies inside the circle, not on it.

Step 2 – Reason: R is true, since $$PC = \sqrt{26}$$ and $$\sqrt{26} < 6$$.
