If both Assertion and Reason are correct and the Reason is a correct explanation of the Assertion.

(A) Both Assertion and Reason are true and the Reason is the correct explanation of the Assertion.The reaction proceeds as follows:$M + HNO_3 \to MNO_3 + [H]$ (Nascent hydrogen)$2HNO_3 + 2[H] \to 2NO_2 + 2H_2O$Overall,the nascent hydrogen produced by the metal-acid reaction reduces the nitric acid to nitrogen dioxide $(NO_2)$.

Assertion : When a metal is treated with conc. $HNO_3$,it generally yields a nitrate,$NO_2$,and $H_2O$.
Reason : Conc. $HNO_3$ reacts with a metal and first produces a metal nitrate and nascent hydrogen. The nascent hydrogen then further reduces $HNO_3$ to $NO_2$.
