Question

Directions : Each of these questions contain two statements, Assertion and Reason. Each of these questions also has four alternative choices, only one of which is the correct answer. You have to select one of the codes (a), (b), (c) and (d) given below.

(b) Assertion is correct, reason is correct; reason is not a correct explanation for assertion
(c) Assertion is correct, reason is incorrect
(d) Assertion is incorrect, reason is correct.

Assertion : When a metal is treated with conc. HNO₃ it generally yields a nitrate, NO₂ and H₂O.
Reason : Conc. HNO₃ reacts with metal and first produces a metal nitrate and nascent hydrogen. The nascent hydrogen then further reduces HNO₃ to NO₂.
