Questions number 19 and 20 are Assertion and Reason based questions. Two statements are given, one labelled as Assertion (A) and the other is labelled as Reason (R). Select the correct answer to these questions from the codes (A), (B), (C) and (D) as given below.
(A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
(B) Both Assertion (A) and Reason (R) are true, but Reason (R) is
textbf{not} the correct explanation of the Assertion (A).
(C) Assertion (A) is true, but Reason (R) is false.
(D) Assertion (A) is false, but Reason (R) is true.
Assertion (A): A ladder leaning against a wall, stands at a horizontal distance of $6 \operatorname{m}$ from the wall. If the height of the wall up to which the ladder reaches is $8 \operatorname{m}$, then the length of the ladder is $10 \operatorname{m}$.
Reason (R): The ladder makes an angle of $60^{\circ}$ with the ground.
(A) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A).
